Headers + Exhaust For a VZ.

[Critical Jim]

Greetings all.

Finally decided to get an exhaust system for my VZ v6, looking to go for a 2.5 inch bolt on exhaust and then a set of headers a bit later on down the track.

Been quoted $300 for a Lukey 2.5 cat back system, and $460 for a set of Pacemaker headers both prices are unfitted.

Would I need Hi-flow cat's or would the standard one's fit in-between the headers/exhaust, I'm not looking for an increase in power, just a better note.

Cheer's.

i have an o5 vz sv6 i put a 2.5 single cat back on mine then got a set of genie headers and havn,t changed the cats ..it gives me a good note and more power and with a k@n filter it was dynod at 199 rwh on prem 95 i have been told to only change the cats if i was going to race it but even then it wouldn,t make that much differance

Decided against getting a set of headers and just went for the 2.5 Lukey bolt on system with a nice shiny stainless tip.

Ordered it this arvo, collecting it tomorrow, should be bolted on by weekends end.

Just went with the cat-back exhaust in the end, decided I didn't really need headers for it so I cannot tell you sorry.

is your car a 175 or 190? how much it cost you to get it all fitted and is the note any better?

[MRSHL]

how much that set you back and whats the note like from it?

Hey are you aware of which vehicles have which engine? Obviously you are not. If the persons ride description is a V6 VZ and its not a Calais or an SV6, then its a 175kw engine variant. Do a little bit of research mate. Knowledge is power and you have to work for it.

Where did u get that price? tempting...

well mate i was under the impression that a commodore to the acclaim models were 175 and above were 190....but the bloke didnt say if it was 175 or 190. im sorry i didnt read what sort of car he actually had, on further investigation i realised he had an acclaim. why the hell you so negative. and i still stand by my question to CRITICAL JIM...what does it sound like now and how much that set you back?

[MRSHL]

hey guys got the car booked in for a system to be hooked up, 2 1/4 twins to 2 1/2 twins. but i got a question. do you need to change the headers to get a descent note out of it and get the most out of it or not? and will geting a k&n air filter make it breathe better giving it a bit more up and go?

best exhaust ive heard is a 2 1/4 xforce cat back. loud but not to loud, and no loss in power.
