Hi Boys,

I hope I'm not revisiting an existing question!

I have a full factory sports exhaust (hmm.....) fitted to my 380 LX, so I am told but doesn't sound like it, looking at the Berklee BS0655 as suggested by blue 380 and grubco (hope I got these right). I'm in ballarat and had a lukey on my TH is this the way to go. Deff want to keep my quite highway level but I want a growl as well.

let me know boys, you seem to point me in the right direction. K&N on the way.

I purchased a Supercat BSTR003 and it will give you what you want. Not loud while on the highway but has a nice tune if wanted. Shoot recommended this one and i am happy.

Yeah I have the Berklee model on mine, though I also had a Lukey on my TE (and it was LOUD).
I found the Lukey (at least on a Magna) was very very loud. I couldn't drive quietly if near a cop car, etc, and it tended to drone - but at that time I loved it! Great idle rumble too.
Whereas the Berklee is much quieter but still has a growl to it when you put the foot down. It also has a nice sound when cruising (freeway, etc). Idle is much quieter, but you can still hear something is different.
I guess if you don't mind the louder sound with possible drone, go the Lukey. If you hate the drone and want something subtle but still growly, go the Berklee. I'm sure either way, you won't regret chopping off the standard muffler.

I ordered in the Lukey, but we held it up there and it wouldn't fit. So I went with the recommendation from the guys at Rightprice exhausts. I'm very happy with it.

Its weird though, they seem so loud after you have a muffler fitted, but all the GEN3 drivers say its quiet on the inside. ( I've heard it in a tunnel, Quiet NO).

Mine growls when you put the foot down, a light rumble when cruisin, the model I got is in my Profile.

But thats for a muffler, if you want an exhaust system, and power, look at Foozcool. Twin system from the cat back (??? maybe removed) and a chip to manage the ECU, Bout 170 KW @ the Front Wheels.:gtfo:
That I would like to know the total cost of. Thats about as much power as a F/I 3rd Gen.

I got the wheels & exhaust done by the dealer when I bought the car & was about $4.5K so not sure of individual costing. I still have the main cat under the car but the major difference is the extractors which removes two cats from the engine pipes for greatly increased flow. Add the intake, k&n, throttle body & chip on the best fuel & yep you can have 170 KW ATW too! There are pics buried somewhere in an old exhaust thread of my setup.

Just on that note have a look at what the DOHC's in the US are pulling with tiny mods. Certainly excellent engines (both ones).

Do you know of a similar forum in the states that talks about mods for the mivec galant? I'd be interested to read the performance differences between our engines with just a few mods.

Going to see the local guy at carline, that did my TH exhuast on Sat.... See what he says I am thinking a twin pipe berklee would be nice, Couldn't find any info on the supercat and a quad pipe is a bit excessive for my liking, thowe it does look fantastic.

(Will be getting the headers from RPW when I can afford it, remember I am also building the stereo, not as easy as I thought)

Will see how we go

Forgot to mention I had a full "sports" system on my Magna, to which I was referring to as loud, including Pacemaker headers.
On my 380 I have only changed the rear muffler because many people here said the rest of the system is quite good - but I have always been curious what a twin system (ie 2 pipes out back, 1 either side) would cost, including modding the rear bar, so please let us know the details if you get a quote for such work.
Also, could you put a pic of your car in the profile? Would be nice to see if not too much trouble.

I just posted this elsewhere, but if you're after a twin exhaust, TMR will be doing a TMR380 twin exhaust kit in the near future along with brake, suspension & supercharger kits if you can wait. The info will be posted on their website when available.

I use www.3si.org. The DOHC they talk about on there will differ too greatly to be relevant to you i believe. Pretty out-dated engine, no mivec etc.

It's obviously got the TMR380 pictorial but mainly have EVO parts & accessories.

Once the 20 TMRs are done they will be offering all the gear as kits via their website.

I also have the problem of choosing an exhaust. In NZ none of the mufflers recomended are available, Ive narrowed the choice down to either a flowmaster or a superturbo, Thats all thats really available here unless you want a rice rocket cannon . I wonder if a VRX muffler off a diamante will fit.

PS. The difference in performance on a cold frosty morning is very noticable:D

All the gear, eh? Someone previously quoted a sub 1K price for the body kit. Any ideas how much the exhaust additions will be? Also, if the supercharger fitment's up for grabs, then I'd definitely be one of the first in line for it!! My lack of mechanical experience would probably mean begging for the dealer to fit it for me, though. Plus the warranty issue ...

Dunno, I spoke to Alan down there & he said just keep an eye out on the website.

The supercharger kit will be available, apparantly they have another computer which runs the supercharger & talks to the factory ecu. I'm in Brisbane & asked about fitting & he said he has people that could do the installation up here but it wouldn't be Mitsubishi.

Hi Guys,

So I went to carline, guy puts it on the hoist and what do you know apparently my muffler is not stock or factory.

So here is my problem It doesn't have the sort of note I am after!

"Easy replace it"
You might say, but he couldn't tell me what brand or model it is. So I have posted some pics to see if any1 can help.

Sometimes being this pedantic is a real pain.

Dunno, but it looks like my original muffler too (with the "buldge" shapes either side of the tip).
I take it you delayed the replacement of your muffler.
My advice, just rip it off and turf it. Go with any of the brands we have mentioned here, and I'm sure warranty will not become an issue.

Wonder if its a straight through or not?

Grubco
08-06-2008, 03:48 PM
No, the standard muffler definately is not straight through. I heard it contains two 's' bends within before the exit. It has an okay sound, but an aftermarket one will sound better and unleash more power.

08-06-2008, 07:32 PM

I'm surprised the guy from the exhaust shop couldnt tell what type it was after getting under the car & having a look.

Easiest way to find out if it is a stright thru is stick something in the muffler (like a garden hose?) & see if keeps going in. If it stops suddenly, there is a pretty good chance its not straight thru.

Sorry if a bit off topic here but great job on the mods mate, it appears you have released some very good power out of the 3.8. 170FWKW is a great result!! I suppose with drivetrain loss you would be looking at somewhere around the 210kw at the engine??

I still have a major soft spot for the 380's. How do you find the torque steer with the increased power? Do you have any idea what your 0-100 or 400 metre times are now?? Has it lowered your fuel consumption?

My recent mods to the R8 should have lowered my fuel consumption in theory but I find im putting the foot down much more just so I can hear my new exhaust :nuts: :nuts: :nuts:

That put the argument I made to my wife about the mods making the car better on fuel right out the door....:bowrofl:

Using the normal 3/4 rule I would have 227 KW at the engine??

It's not really torque steer as the 380's have 50/50 drive shafts, its more tracking on even surfaces under power. It's a good idea to have both hands on the wheel if giving it a bootful especially passing on the highway. As long as you're ready for it it isn't an issue, doesn't throw you off the road or anything.

Not sure on 1/4 mile time but would have to be down lower in the 14's at least.

So how's the R8 going, mods feeling money well spent??

227Kw's!!!!! 225Kw's is where the VX SS's were in 2002 out of the 5.7!!!!!!!

Great stuff!!

The R8 feels like a different car altogether after the mods and edit. Much smoother acceleration.....it just keeps you pinned to the back of the seat all the time now :D

Though I am still getting used to the exhaust. Its just a "bit" louder than I had expected and does suffer a little drone between 40-60kays. Up over 80 though and cruising its quiet as a doormouse.

Under full throttle its real sweet lol

Awesome stuff!!:badgrin:

Forgot to mention before that the fuel economy remains pretty well unaffected, can still get into the low 8l/100km.

Although I only got another 6kw atw on the 100 octane fuel tune, the torque down low has seemed to increase quite a bit, very easy to spin the wheels now.:D

Yeah... video tape can never compare with real life, especially YouTube's lower bitrate audio - perhaps a drive-by blast would sound better (one day...). But the main thing is that gains are really there to be found if the standard muffler is changed.

I did mine at Penrith Muffler Man (naturally in Penrith), so if you're round-about Sydney's west I can recommend them. Blue 380 did his there too, so that's 2 endorsees for you. And we both have the same muffler, a Berklee BS0655, apparently the only muffler dyno-tested specifically for the 380. It has a good sound, but not too loud.
And he will retain your tip too.

I don't know about the extractors, but I guess they do - but I don't know what brand/s. They've been in business ages (ie over 20 years or something). If Blue 380 is reading this, perhaps he can fill in some answers; he has been a long term customer there I recall.

Not really sure there. Assuming both mufflers are of the same dimensions, sound would probably be similar (smaller muffler would be louder) - so I guess the non-dyno tested straight-thru muffler would rob you of a few kilowatts (ie would feel like standard muffler) and show no fuel and power difference. But that's a guess... perhaps someone else can offer some real facts here.

Not sure about the extractors...I've read here RPW are the only ones doing extractors for a 380 however someone said they are actually made by Liverpool Exhaust. I got my first exhaust done at Penrith Muffler Man in 1985 which was a Datsun 180B and I've gone there ever since & they have always done a great job.

As far as the dyno testing goes, I think it just means when the muffler was designed they dyno'd it to ensure they were getting the best power gain out of it.

MadKonfusion, you are welcome to take my car for a spin if you want to find out what it sounds like before buying one. PM me if your interested.

Has anyone looked into doing twin exhausts on the 380?

I know there is space to put another muffler but i would have to cut out the rear bar to match the factory cut out!

I want the quad tailpipe look but my concearn would be power gains ...... or losses?


Do any of you guys know the "science" behind it? i was looking at the berklee mufflers like the ones being used by some members but with single inlet and twin tailpipesnot just a single outlet and twin tip!

Twin exhausts are no problem (split from the third cat back). Foozrcool has them fitted and he certainly isn't suffering any sort of power loss :badgrin:

Main thing is the straight through muffler/s.

I investigated a genuine twin system from each manifold bank, separated (except for a balance pipe) all the way back through to the tail pipes.

My exhaust shop told me it was extremely noisy and drony and the power gain would only be worth it for racing.

Do you know of a similar forum in the states that talks about mods for the mivec galant? I'd be interested to read the performance differences between our engines with just a few mods.

Not the MIVEC Galant, but the Eclipse uses the MIVEC 6G75, and is more likely to be modded than the Galant.

Eclipse forum here:

Includes mention that they got a 6 SPEED manual variant for their '75's :rant:

Has anyone looked into doing twin exhausts on the 380?

I know there is space to put another muffler but i would have to cut out the rear bar to match the factory cut out!

I want the quad tailpipe look but my concearn would be power gains ...... or losses?


Do any of you guys know the "science" behind it? i was looking at the berklee mufflers like the ones being used by some members but with single inlet and twin tailpipesnot just a single outlet and twin tip!
Yeah when mine was up on the hoist (to change the springs) I had a good look around and there is definately enough space for another exhaust line on the left - but like you I realised the plastic bar would have to be cut. This would either be done "bodgy" or "properly", that is you could cut the same-size arch-shape into the bar but there'd be no 'eave' behind the cut-out like the current one has (I can post a photo if no-one knows what I'm talking about). So my question has been: where is this work done, and how much would it cost? (Probably some fabrication work involved... = $$$$)
Other than that, I think gains would be good as the exhaust line goes straight down the middle of the car (unlike older Commodores which used to bend and twist left and right), so distance to either muffler would be the same. And with 2 straight-through mufflers, the 380 would look and sound awesome!
If anyone is planning/doing this, care to leave some info?

There is also someone up the coast that has the duallies. Saw a black VRX or GT at Moffatt beach area. Looked nice

I recall from the very early days here, a silver GT or VRX had dual pipes too (the photo shows it parked in a tiled garage) - probably in the archives somewhere... but again I don't recall any details of how its done and how much it costs.

Wow, you have the same financial advisor as me!
Best tactic is the fuel angle... if a mod can save money on fuel (with or without hard evidence, hehe), then onto the table the discussion goes.
I believe bigger rims can save petrol too!

From my previous post of a silver 380 with dual exhausts, I found this old thread from 2006.

Can any South Aussies who have had the Berklee (or any other straight-through) muffler fitted recommend somewhere? Preferably Southern Suburbs, but it doesn't really matter.

Anyone? Have no South Aussies had a new muffler fitted?

Haven't had mine fitted yet. Will be calling around early next week for quotes.

Cool, let me know how you go mate.

I emailed a few places today to see what they say, will let you know what they say if they get back to me.

Had a response back from AAA Exhausts at Richmond:

"Pricing is hard depending on how much pipework we have to change, But if we could just cut original muffler out and replace with the Berklee one the cost would be $150.00. But if we had to modify your pipework the cost could get up to around the $250.00 mark."

So the question is, are there any pipework changes required on a 380 SX?

No it's a simple bot on job shouldn't need to cut anything.

Grubco
01-08-2008, 02:17 PM
Yeah, no cutting required. Mine took about an hour; some tiny fiddly work required with the bolt-on match up.
EDIT: Oh yeah, price. Mine cost $140, from same place at Blue380 ($8 less than him for whatever reason) and also retained my chrome tip.

I've got the Berklee & it cost me $148 fitted (I re-used the chrome tip).

I just posted this elsewhere, but if you're after a twin exhaust, TMR will be doing a TMR380 twin exhaust kit in the near future along with brake, suspension & supercharger kits if you can wait. The info will be posted on their website when available.

Great googly moogly.
I had a look at their site, but nothing there yet...

Any idea when it will be available.

Hell I don't even care about the supercharger (insurance comanies then let the hounds out :doubt: ) but the twin exhausts and suspension I'd buy in a second.
