hay guys hows it all going well i decied on my exaust system(twin 2.5" catback) a highflow pod filter (not sure on this 100% open to sugestion) and i want it get it chiped but noidea on this so help is need lol

[Not_An_Abba_Fan]

Is it a V6 or V8?

[Smallies]

I've got a pod you can buy if ya want - http://forums.justcommodores.com.au/...od-filter.html

(but If i was you I'd get this Yella Terra Cai)

Is it a V6 or V8?

IMO whether its a 6 or an 8 is almost irrelevant.

Exhaust, Chipped and a better intake will be low cost improvements on both a 6 or an 8.

When it comes to exhaust you can pretty much do what ever you want - Extractors will help a bit aswell, my Caprice has a full stainless custom twin 2.5" with no mufflers - just a resonator, all fed from pacemaker extractors.

Intake can be either the pod , the Yella Terra CAI or an SS Inductions or HSV CAI.

And with Chip (this is why i said 'almost irrelevant') you get either a V6 or V8 memcal chip, from a well recommended tuner, i havent travelled down this path yet, but plan to soon - dont get one from ebay.

[Not_An_Abba_Fan]

It is very relevant actually. A tune would be the best mod for a 6, the 2 1/2" twin would be absolutely useless, and the pod would do next to nothing apart from make noise.

On an 8 it is totally different.

[Smallies]

Every little bit helps lol....

He didnt say he wants either and exhaust, chip and better intake... which is best bang for buck?

He said he wants all 3, so whether its a v8 or v6 doesnt effect his question....I just gave him a little help and showed him some options.

thank mate it is a 6 the reason for the twin 2.5 inc is partly the look to lol thanks for ur help now i live in gympie about an an and a half from brisbane dose any one reccomend some to fit and install a full exhaust kit??

[Smallies]

If you are after the twin look, but wanna save some $$, whats wrong with a single system with a twin tip?

That'd be the go.

[holden_calais_VT_1999]

ok did a lil looking round on the site and theres a lot about exhaust i think ill do a lil more reading on it befor i go buy one lol

[D-Man]

if you have twin exhausts on a v6, that's 2,5" each... forget about going out of the driveway in a hurry. you'll put down your foot and it will be like a grandpa's fart... not cool + you wont go anywhere there just wont be enough back pressure.

stay with single pipe installation but maybe twin tip... definately not twin pipe.

there was a tool down here in melton who had twin 3" on a v6. was hilarious. he put his foot down and i was sitting in 1st gear for a good 7 seconds - 0 - 50ish cause that's how fast he was going haha. then just took off onto the highway. the car had a shit load of noise but no go AT ALL! just hope for his sake he was putting a v8 in that shortly after.

[Smallies]

Single 2.5 inch system with twin tip fed from some pacemakers would be you cheapest, best sounding solution IMO.

[holden_calais_VT_1999]

ok cool did some readin up on it today and read a lot of different apion on catback system just wondering wich is a better system to get more power out of my car rather than noise (added bouns if i get the right sound to)

Actually, it won't go because there is too much back pressure. Not having any back pressure is the ultimate goal.

The exhaust slows down too much in a bigger system and loses velocity. As the exhaust slows down the next pulse banks up against it and so forth, so the engines compression is what is pushing the exhaust out, not the exhaust scavenging effect dragging it out. The result is a lack of low down acceleration and using too much fuel.

wow thanks for that mate so in your opioun whats the best one to get the most out of my engine

[Not_An_Abba_Fan]

I wouldn't go any bigger than a 2 1/2" single. In fact the stock system is the best size, but the mufflers are restrictive. It would cost more than a 2 1/2" bolt on system to change the mufflers in the stock 2 1/4". I can do you a bolt on 2 1/2" at a good price, how loud do you want it?

[holden_calais_VT_1999]

ok cool so ill buy a 2 1/2 inch catback system with pacemaker extractors (sound sorta like a v8 but not quite as loud dont want to be a cop magnet)

[nathan549]

no v6 will sound anything like a v8. i wanted the v8 sound aswell in my vt II spack. so im just leaving it performance wise for now and working on the looks first (i want to spend quite abit of money on it to the way i want it to look and perform without saving up and buying a new car in the future).

but yeh itl still sound sick just not that v8 sound . redback or lukey systems seem to be the best exhausts these days

[holden_calais_VT_1999]

ok cool thanks for that mate everyone has been a big help on this
