Hey guys, just fitted a powerflow stainless muffler to my car, let us know what you think!

Camera sound quality doesnt do it justice as per most cameras seem not too...

You didn't want the VRX tip? Looks different with standard pipe, but sounds beefy. Looks like you almost blew the camera (phone?) away with one of those revs.

how much $?

To be honest I completely forgot to mention to the mechanic to fit the original big tip so i'll do that next week. I am pretty happy with the note, not to loud in normal driving but nice and deep when given a bit. And yeah haha the camera nearly went for a tumble

how much $?

$190 bucks fitted mate. I thought it is reasonable for a stainless muffler. Getting a tip fitted next week cause a certain silly someone forgot about it when booking in their car for a muffler :doh:

Sounds so good

bargain

bargain

Needless to say im happy as punch at the price

Sounds so good

Amazing what a simple muffler can do :happy:. Shows how much better the rest of the standard system is compared to falcons/commodores

Yep! that does sound good!

That sounds unreal!!!!!

Does it drone? Did you notice any performance gain?

That sounds unreal!!!!!

Does it drone? Did you notice any performance gain?

Cheers mate! At town speeds ever so slightly, due to the auto selecting 5th as soon as it can. But other than that it is not noticeable whatsoever. Id have to run it for a bit before I notice any performance gains but its safe to say any sort of exhaust mod is going to have a positive effect on performance

How much noisier do you reckon it would get if you fitted extractors? Taking 2 cats out of the equation could make it hell loud! I can't make up my mind what to fit first,muffler or extractors

How much noisier do you reckon it would get if you fitted extractors? Taking 2 cats out of the equation could make it hell loud! I can't make up my mind what to fit first,muffler or extractors

I'd say there would be a large noise increase. However I never really considered extractors as my mitsubishi dealer will not allow them under warranty, a muffler is quite sufficient for now. The standard mufflers on the 380's are massively baffled so they do cut alot of sound out. So far as I can tell the rest of the standard 380 system is pretty good quality....I havent seen to many falcons or commodores that sound nice with just a muffler change, but I could be wrong?

That sounds so good on the video that I am tempted to get one. I would like to hear it in person first but considering you live about 1000km's away, that aint going to happen:D

That sounds really beefy! Like the noise when you back off the gas too.

From my experience there is a lot more noise when you put the extractors on, taking the precats out of the loop maks a hell of a difference.

Shame all these 380s are scattered around the country.
If only we could gather them all in one place to hear and check these new mods face to face.

When I drove your car (before you gimped it :P ) I didn't think it was much louder than mine but I thought there was more engine vibration through the steering wheel and cabin generally.

Yeah you are probably right, mine was just right before the extractors & then got louder with more drone/vibration through the cabin as you said. My first effort with the metalcat & new system was stupid loud, droney & quite annoying. At the moment it is ok but still a bit barky & loud for me.

That sounds so good on the video that I am tempted to get one. I would like to hear it in person first but considering you live about 1000km's away, that aint going to happen:D

Haha yeah there is a tad of a distance issue there. Its a lovely note in person mate. Burbles nicely when downshifting manually and as it wears in a bit should crackle a tad...well hopefully!

Hopefully when it wears in a bit the crackle when backing off should become more noticeable

Very tempting.
I'm wondering, how much power is lost by upgrading to a twin system?

Grub,

Far as I can tell, the only time you would lose power is if you go to a full split system from the exhaust manifolds/headers without an H join between the two pipes. As apparently mytsgt95 found.

If you go for the same type of system I have, single pipe most of the way splitting into two after the petrol tank, there is no loss of power at all, providing you use straight through mufflers.

I wouldn't think there would be any even if you put triflow mufflers on as you will have nearly twice the flow with dual outlets. (or should I say half the restriction)

please if you do get a full length twin system get an x-piece fitted. 1) it sounds like poo without it 2) mine did feel alot perkier once the x-piece was fitted.

could you get a similar exhuast note (from just a single exhuast) on a stock 3rd gen?

that sounds awesome mate. I would be a very happy camper :)

I got my muffler replaced last week with a berklee, very impressed so far :happy:

I wouldnt be surpised that the VRX and GT models were meant to have a sports muffler at the time of the release, but were removed due to cost restraints. Same as the galant intake.


Food for thought....

What sort of cost are we looking at to fit a new berklee muffler.

probably around the $250 mark for the berklee

Is the Berklee a stainless steel muffler? That sounds a bit pricey if it isnt?

It's not stainless steel, it's mild steel.

And $250 is the cost of the muffler & fitting, as it's not a bolt up replacement & cutting & welding is required.

Gees that is a bit more than mine was fitted then, and i also had to have a few things welded. And considering mild steel will not last nearly as long as the stainless.

Forgot to point out that $250 was just Braedz's guestimate, which sounds about right to me. But if you shop around you might be able to find a place which will supply & fit the BS0655 for a bit less than that.

Also, the BS0655 is on the Best Mufflers web site for $110 & shipping. That may or may not be less than a muffler shop can get it for.

probably around the $250 mark for the berklee

That was just a guestimate, as KJ pointed out.

Mine cost $148 fitted however I retained the old chrome tip.

why does every one go berklee?? i dont think ive seem anyone with a lukey or redback yet??

Yeah mate,look in the other muffler thread!

Yeah mate,look in the other muffler thread!

yeah just looked in that after i posted lol

My Berklee was $140 fitted with my original tip (though that was almost 2 years ago now).
My reason for getting it: it was recommended to me as the only muffler extensively tested for the 380 (aparently it was going to be supplied with the 380, but missed out right at the end for some reason). Also, it is fairly quiet and doesn't drone.

why does every one go berklee?? i dont think ive seem anyone with a lukey or redback yet??
I was talking to the guy who has done my exhausts in the past an explained to him that I wanted the car to breathe better but not to be noisy (= cranky wife!) He suggested a redback baffled sports muffler for around the $140 mark. I think I will be doing this. It will be a bit noisier but not that bad and still give alot better flow. Anyone gone for something like this?

why does every one go berklee?? i dont think ive seem anyone with a lukey or redback yet??

380's already have a walker system in them. the only reason for a lukey is if you want more noise.

They may have a Walker in them (I wouldnt know) but it is definitely not a "straight through" muffler.

I have a Lukey Ultraflow on my 380 which is a straight through (you can see right through it) but it is a bit too droney for my liking. Would be great for constant spirited driving though.

I listened to the Redback when I went to audition mufflers, it was actually deeper than the Lukey but I dont know what theyre like welded on and sat in the car.

I'll be sticking a Berklee on in the next month or so.

You will be very happy with the berklee, no drone at all, but has a nice note when you put your foot down.

How much louder than the standard is the berklee. Does it get louder with age as someone was saying?

Its not that loud at all. The muffler I have was previously on KJ380s ride. I am not sure how many Ks he did with it on though. I have done around 2500ks with the muffler and havnt noticed any difference with the noise at all.

How much louder than the standard is the berklee. Does it get louder with age as someone was saying?

The Berklee is louder than the standard one, but not too much (The YouTube video I made to demonstrate this, failed miserably).
It depends what you want. If you want a deeper louder sound, you may be unhappy with the Berklee. But if you just wanted a bit of noise - and no drone at all - from a straight-thru muffler, the Berklee will be good.
And they do get louder as they age. I wasn't too impressed with it all when it was new; I couldn't hear much difference at all over the original one. But over time it gets a bit louder and deeper. I reckon, if it made the noise that it does now, back then - then I'd have been much happier with it.
As I recently mentioned elsewhere, my wife has "commented" a few times about my 5am start-ups. I used to like a few minutes idle time, but she complained about the noise and reverbaration coming through the house from the garage.
Bottom line, I'm happy with it (wouldn't mind a bit deeper, but have no plans to change it now) - and I think all the other Berklee owners are happy with theirs too.

Had I not wanted a stainless steel muffler I would have taken the berklee without hesitation. Tried one on before getting mine and it does have a nice note which is drone free, recommended!

As Grubco mentioned, the Berklee does get louder but I still wouldnt say its a loud exhaust. Check out post #347 on this link to hear about 3 seconds of my car doing a drive-by (kindly filmed by Dave Grubco :D)

We should meet up again, and this time I'll bring my video camera for some serious footage, rather than playing around with the phone. Some good open roads out there as I recall.

Call me an ol fart if you like, but I kinda like the quiteness of standard but it is a bit on the asthmatic side if you know what I mean. Alot of you say that they let you hear the muffler before they fitted it. Did any of you guys compare different ones and what were they like. I am particularly interested if anyone tried a baffled sports type.

I am an old fart too, thats why I liked the Berklee because it gave a very good performance gain & only made it a little louder than standard (when first fitted).

I also got to sample a few mufflers held in place prior to welding and originally went with a Swift straight thru. It sounded pretty good standing next to the car when held in place but when I got it fitted and drove away, it was that loud and droning inside the car it gave me a headache within 5 minutes. I pretty much couldnt drive the car for a few days (because it was so loud) until I got booked in to get it replaced with the drone-free Berklee. I would therefore STRONGLY suggest to anyone sampling new mufflers, get inside the car when they hold the muffler in place and rev it because you dont notice the unbearable drone from outside the car!!!

EDIT: 380 matey, not sure where you live but I'm from Leonay so if you're near by, you are welcome to take mine for a spin to hear it in person.

yeah I have an exhaust leak from the muffler ;)

so a part no and if you are not shy the cost would be super :happy:

Been 6 or so months since Ive fitted it and still have not had the chance to go in and get the number from the mechanic as he never actually told me what it was....HOPEFULLY this week I can get it

As for drone I would not say it drones , you do hear it when it drops into 5th at 60km/h but its hardly droney or annoying...Although this is the only real car ive been in thats had exhaust mods so I cannot really say I know what a bad case of drone would be...

yeah I have an exhaust leak from the muffler ;)

so a part no and if you are not shy the cost would be super :happy:

What you talkin bout exhaust leak, that's Mitsubishi musical goodness your hearing there :P

No part number at this stage mecha...went through a mechanic I know so didn't really ask at the time but will get one asap. As for price it was $190 fitted w/o a tip. I thought that was reasonable for a stainless muffler yeah?

190 man thats good

Yeah mine was about $200 about 2 years ago, or whatever, so yeah good price. Good sound too (good drive-by video too).

Alright fellas the part number for the muffler is H14OC250M

Brand is Powerflow

Cheers :beer:

It's only 14" X 8" X 4", i.e. not very large, which in my experience means welcome to drone city.

I'd be pleasantly surprised if it didn't drone.

If you really want a Powerflow SS free flow muffler I reckon you'd be better off going for the 20" x 10" x 5" size, see this page:

You are right KJ with the dimensions...but I havent done anything else besides the muffler so there is still the rest of the system there to restrict noise i.e drone is not a problem..once I do extractors and a high flow cat I'll be looking at a much larger muffler. What are the dimensions of your SV6 muffler's KJ?

I just found out that they are like 10 mins down the road from my house

I will have a chat to them tomorrow me thinks

and 175 thats heaps cheaper then i thought

Mikey,

My mufflers are 14" x 8" x 8" (i.e. round cross section not oval) or 896 cubic inches.

My exhaust guy reckoned that 14" long was all that would comfortably fit under the passenger side due to the fuel filler pipe being in the way.

But Fooz's Supercats are apparently a fair bit longer, and they are obviously oval. I'm guessing 18" x 8" x 5", which comes out at 720 cubic inches. He hinted in another thread that a little 'denting' of the passenger side muffler was needed before it would fit.

So if my guess is right my mufflers should be a little quieter and maybe less droney than Fooz's.

Fooz - can you let us know the dimensions of your mufflers?

KJ they are actually 18" x 12" x 6.5" straight throughs. They didn't dent the muffler it was just a suggestion if the fit was real close & in the end they fitted ok. I don't have any drone at all now but I have put extra resonators in at the front.

That's plenty big!

Works out at 1404 cubic inches, way more than mine.

Might have to look into a pair of these.

Can you post up the part or model number (sorry if you've already done so in another thread).

Not sure of part number but looking at the Supercat website I think it maybe the SCM8802 (11 by 6 Oval Mega Flow) which is actually a 17" x 11" x 6". My measurements were external dimensions & they probably quote the internal without the seams etc.

No mate have no idea, I just kept going back adding & changing until I got it right. I've probably spent about $2500 on my system including extractors with all the different setups I have had over the life of the car.

Very happy with the current setup though :happy:

Nope not stainless. If you like the setup I'll tell you where to go get a setup the same on the Northside of Brisbane.

Doesn't look like they do stainless in the BIG mufflers.

Oh true, well I guess I don't do many short trips so moisture sitting in the muffler shouldn't be to much of a problem. Mate at this stage its purely talk, uni budget limits most things past servicing costs lol
