VZ Exhaust

[Aussie_VZ]

Just a quick question hope someone can answer.

I have a mild steel 2 1/2 exhaust.
Im taking that off and installing a full system pacemaker headers high flow cats
and 2 1/2 s/steel exhaust NOW,

What would be more suitable, with a resonator or without a resonator?

Can someone let me know?
I don't know whether it would be to loud without it and more powerful or the other way around with the resonator on there and still sound very nice and still power to the rear end?

Can you get more power without a resonator as the exhaust gas goes straight through?
or will it be just to loud not having one there.

If i get get some opinions on this that would be awesome.

thanks

P.S I hope i made some sorta sense with whats above

[Aussie_VZ]

Surley someone must have some sort of advice?
I call exhaust specialist and they givme 2 different answers?

Which lead me to ask here..

It's going to be loud and raspy and drone like buggery. Even with the resonator.

There are two resonators under the front that look like cats, you need these to take out the crappy note.

The alloytec is a small, high revving engine, you will get better torque with the extractors and cats, but it will sound like shit with a single 2 1/2" system.

[Aussie_VZ]

Not getting a single I'm putting on a twin

[Not_An_Abba_Fan]

With a twin it will sound deeper, but you will lose a heap of bottom end torque.

[Burto89]

So would a twin 2 1/4 be a better option for a cat back? Straight pipes? or a muffler? Anyone got some video of their setups?

Sorry to high jack OP but i thought to save a new thread!

[Not_An_Abba_Fan]

Twin 2 1/4" would be better. Running into a single 3" after the front mufflers is better again.

[Aussie_VZ]

Im getting the new pacemaker headers new cats and twin 2 1/2 s/steel exhaust in 2-3 weeks.
I will post video of it once its done

Going too big you lose back pressure and lose bottom end torque, makes the car doughy and will also use more fuel because you're putting your foot down more to get the car to go. A larger exhaust will only help at very high rpms because it'll let it breath better when trying to dump the exhaust gases.
Too big and as said above you'll get a crappy loud drone sound, been there done that :P

Just today a mate of mine who has a vz sv6 got his exhaust finished yesty arvo and it sounds absolutly awesome.

and he put the pacemaker headers high flow cats and twin 2 1/2 s/steel exhaust on it.
which im also doing in a few weeks.

and it kicks my current exhaust up the ass the one ive got sounds like a vacuum that needs an overhaul.

i wouldnt say 2 1/2 is that big for a v6 considering it has a descent size motor in it.
and i wouldent go over 2 1/2 exhaust unless it was an 8

[Cod]

If you want the 2.5" go for it :P But keep in mind you're doing twin, so it's only 3 cyl per 2.5" pipe, that's a 1.8ltr engine with a 2.5" fitted.

[BullittSV6]

It all depends on what you want your exhaust to sound like. If you want it loud, go the twin 2.5. But several exhaust shops I have spoken to have all said to go with a 2.25 as its the best for the alloytec. Its got a note, its not going to get into trouble with the cops, and it doesn't harm performance.

NAAF.. you may be able to answer this.. What is the difference between a sedan exhaust and a ute exhaust. Are they interchangeable? Would you be able to modify a ute exhaust to fit a sedan?

The reason I ask is that I have found an excellent LS1 twin factory exhaust for a ute and I would like to fit it to my sedan. Whaddaya reckon?

An alloytec is a decent size? It's only 3.6L, twin 2 1/2" is definitely too large for it.

The ute exhaust is longer than the sedan, you will need to take about 4" out of the centre section. Also the rear is slightly different as well. The tips are parallel on the ute but have a bias on the sedan, the outer one is shorter than the inner one.

[Burto89]

So after cats go straight to 3"? What with a resi or muffler?

[Aussie_VZ]

Well if its to big what is better 2 1/4?

[BullittSV6]

Well if its to big what is better 2 1/4?

Yes 2 1/4. If you go to pacemaker's website and look for the VZ V6 system you'll see that their system is 2 1/4.

[Not_An_Abba_Fan]

2 1/4" off the cats, into mufflers then into single 3" resonator after that.

Have you heard this set up? Any chance of a vid? Also by mufflers do you mean the existing ones the VZ's have or AM ones?

Cheers mate

[Aussie_VZ]

ive pretty much got the info i needed so mods can close this now

I have fitted this set up, but unfortunately the car has been sold so I can't get a sound file of it. It increased torque right through the revs and had no drone.

It is all AM, twin 2 1/4" off cats, into two straight through mufflers , then merges into a single 3" resonator with twin 2 1/4" outlets.

gday mate, Just wondering how much a set up like that would cost? (roughly of course)
and was it a loud set up?
cheers mate

[Not_An_Abba_Fan]

No it's not loud. It is deep at idle.

This system is $450 plus shipping.

[TODDY...]

Hey... just wordering about doing an upgrade on my VZ alloytec exhaust???

Havent really looked around alot gunna ask some questions first and get some good answers on what exhaust upgrade is best!!!


Hoping to get a deeper, louder rumble noise....
Price range around $500-$750
