Hi was getting some quotes for my exhaust system today
went in with the aim of coming out with a similar but quieter system to Whites.
At the first place i went to they put it up on the hoist had a look and suggested there wasnt room for the dual pipes the whole way, so instead quoted for:
installation of extractors, 2.5" to a high flow cat, then dual 2 inch pipes to either side with straight through mufflers. this totalled $1270 made up of fitting extractors $240, hi flow steel core cat $380 rest of system $650 which part in here am i paying too much for?

the second shop i didnt get a written quote, but he had a longer look and still advised against the full dual system as its only a v6, and again recommended 2" pipe after a single hiflow cat. however his price was around $1450 so we shall forgt him. oh and he said i had to take the bumper elsewhere to get cut:/

essentially what i want to confirm is the full dual system i was looking at is pure wank factor on a 3.8L v6 correct?, im not actually losing anything because i want to do this right the first time (ie just paid 700~ for extractors and then another 480 to ceramic coat them:P)

also have any of the rest of you guys other than white looked at a full length of car dual system or never considered it. if you did did you also have the exhaust shops tell you too hard/no benefit/not enough room?
Finally whats the piping diameter i should be looking at if i went with the first quote? is the guy on the money with 2.5 to cat then 2+2 cat back?

Anyone got anything to add or anything i didnt/havent considered that i should. Oh and exhaust system is totally stock atm if that would affect prices or anything.

also how much too much did i pay for the coating as was the only place i could find in metro perth to do it, and then being me went in and said which would you recommend, so came out with the most expensive (the black high temp one) the run of the mill lower temp chrome finish was around $390 http://www.cicceramic.com.au/index.html

Yes Mods i do realise that this barely scrapes into 380 specific, move it if you must:P

I personally think if you don't want it super loud don't go twins all the way because you won't have room to get enough mufflers/resonators in to keep the noise level down.

I have a 3" metal cat & a 2.5" main pipe splitting into twin 2.25" pipes. My rear mufflers are huge straigh through Supercats & I had a hotdog type resonator in the 2.5" pipe. With the extractors this was way to loud for me once the mufflers carboned up so I now put in two Hurricane 2.5" rectangular resonators behind the metal cat which has kept it at an accepable level.

I know I had a lot of headaches when I went to the bigger exhaust for the blower but am now very happy with it. If you run the twin 2" rear pipes as suggested it will be a lot quieter, that would be similar to my original system except I had the factory 60mm main pipe. Just make sure you get the biggest bodied mufflers you can fit under the back so you don't get that annoying drone.

KJ used a SV6 system from the cat back

Not quite. A pair of SV6 rear mufflers only, the rest of the system is custom

After a bit of experimentation I went much the same way as Fooz. Single 2 and 1/2" pipe through to just behind the petrol tank, then split into 2" pipes left & right. Chopped out the OEM resonator and replaced it with two round mufflers in series, roughly 14" long by x 5" diameter each, in the channel which runs under the passenger compartment.

As Fooz says, the secret is to get the biggest (as in overall volume) mufflers you can that will fit (but still straight through). At the time my exhaust bloke reckoned the SV6 mufflers were the best he could find at a reasonable price, he didn't really look into MagnaFlows or Hurricanes as they are a fair bit more expensive.

where they from a ute or the sedan KJ as they have two different mufflers

where they from a ute or the sedan KJ as they have two different mufflers

Don't know, never asked.

Funny thing is the mufflers that my exhaust guy fitted are 'round' in cross section, but every VE SV6 sedan I see has oval shaped mufflers. Don't recall seeing VE SV6 ute mufflers, or at least I didn't make a mental note of the shape of them.

So maybe I have got the 'ute version'?

I also suspect that although my exhaust guy said they were VE SV6 mufflers they might in fact be SV6 mufflers from the model before the VE (VY?).

I can ring him and ask.

As far as the question of dual versus single systems go for a V6, the general consensus I got was single is a lot easier to fit and ultimately no difference in performance. Dual exhaust is for looks.
If you want a true twin system from the exhaust manifold back with a cross over pipe, I was told it would only benefit on the track and be horrendously loud and sound terrible.

I think white has the same system you just mentioned? Sounds ok though.

If someone just wanted duals for the look, would it be out of the question to have a single straight thru & just the get the exhaust shop to fit a matching tip on the other side that just goes back under the rear bar? By my way of thinking, unless you got under the car you wouldnt be able to tell.

From MCA

We have done quite a few of the 380's as well as we are the only firm who manafacturers extractors for these - and best of all we are in Perth

What we normally do is run a single system 2 1/2" off hte extractors with a high flow cat converter, and then split it into a Y Piece at the rear of the car and then run 2 X 2" mufflers off each side.

The cars sound fantastic, looks great and made impressive gains. There are dyno printouts on our website of cars we have done with these modifications.

Sad news is they are an expensive car to do this setup. Extractors alone are worth around $800 - $900.00 fitted as they are quite difficult to fit up due to there location and cross bar setup. Involves lots of climbing over the top of the motor to get to the rear bank.


Rear exhaust system 2 1/2" mandrel bent, mufflers X2 , high flow meallic cat converter and resonaotr system is around $1250.00

This is not drony, but it does sound very very nice.

still telling people they make the extractors i see:P however looks like they are suggesting the same as the quotes i got.
i take it noone has an opinion on the pricing of the Ceramic coating:P
also noted that i have to specify i want the biggest possible mufflers the shop has available and that will fit. now all i have to wait for is some money. kinda went overboard on the TS this month:P (cant do anything till the extractors back from being coated anyway:(
the resonators in the system, i wasnt quoted on those, whats the rough cost there. it would go ok immediately after the cat and can split to duals across to the mufflers post there?

um not sure on hills and stuf you can often see the muffler so were you meaning strap a whole muffler in or just the tip?
if the whole muffler may as well get the whole system done? plus if it want connected eventually you will have one nice shiny tip and one carbonned up:P

Duals usually split from the cat back on V6's, unless FI. That would be the best way to go.

Ceramic coating is overkill IMO.

Resonators should only be about $30 for a 12" or 16" one.

theres probably a 60-75% chance ill be looking at a supercharger once i have an ecu in, and get my magna back from my brother so i have a daily (or turbo but more likely super) so does this effect the calcs or is it best to stick with the NA standard fro now?
(ceramic coating overkill thats good news means in some applications the must be some kind of benefit:P) - already spent the money, in the phase where you try to tell yourself it was a good idea:D resonators cheap, i like. in fact the whole exhaust system is working out cheaper than i expected. (still not gonna bother with the asstron however:ninja:)

If you're going to supercharge down the track, I would do the exhaust then. Unless you really want it now... :roll:

I see you have an auto, so with any exhaust system, noise is going to be your enemy. Personally, supercharged, I would go with pacemaker extractors, into a 12" resonator, into a high flow cat, into a 16" resonator, into a high flow muffler. I would use a single 3" system, mandrel bent if possible. The duals are for wank really (no offence Fooz :P)

You will have big probs with drone going 3" with the auto no matter what mufflers you use, I tried it.

I'd stick with the 2.5" & increase the rears to 2.25" if you're gonna blow it like mine is.

Want the exhaust now, as ive already bought the extractors, and stock system is in the way. and cant yet afford the FI - fulltime uni:(

do pacemaker do custom jobs? as they dont have a set of extractors for the 380 as far as im aware? is going to stay auto, unless someone actually does the magna final gear ratio switch and can show me its going to work. dont want a manual that revs 1000rpm higher at highway speed. (just means theres less rpm above that point) might have to rethink when i actually do the FI.

So essentially best solution would be to stick with similar to what fooz posted earlier. i really do want the twin system now that ive thought about it so much. if it has to come off at some point later so be it:P bit of wank never hurt. least its not LEDs all over the front of the car:D

I've heard KJ's and reckon it sounded great! Using the dunnydore mufflers should be cheaper than the aftermarket stuff too you would think?

Im going 3" with the blower.

the other way to do duel is come down single then split it around the tyre well. ive seen a couple of people do that.

That's exactly what Fooz and I have done.

AFAIK White is the only 380 owner to go (and stick with) full split system from the extractors.
