IF YOU WANNA REV IT CHEV IT
Your title makes no sense at all mate.
But I would go single 2.5 or twin 2.25

Go twin if you can. Correct me if i'm wrong but isnt the fuel tank in the way for a decent twin setup?

Slightly too big for a 3.6. But probably won't make a massive difference.

Twin 2.5 is way too big.
Single 2.5 is a little bit too big.

There's a difference in how a twin system works to a single. Single 2.5 is probably about right for a single system. Twin 2 1/4 is the go IMO.

Considering the stock exhaust is a single 2.25":
single 2.5" is 23% larger - this combined with mandrel bends and better flowing mufflers will be a solid gain. Get this.
twin 2.25" is 100% larger - this is unnecessary.
twin 2.5" is 147% larger - this is just stupid.
Yes, they use a X-pipe to allow scavenging between the banks which in theory should improve performance. Running a smaller diameter pipe increases the exhaust velocity which also improves scavenging funnily enough. A Twin system might be an advantage if it were smaller (1.75"?) but it's a waste of money getting that custom made when you can get a cheap as single 2.5" and get a similar gain and still have acceptable noise levels.Originally Posted by soop
The other thing is that twin systems tend to sound shit on V6s.

ok guys rang a local exhaust shop and they said single 2.5 way to go because it generate needed heat with will prevent the build of of condensation and stop it rusing it out and cracking wich make sense to me he quited me 490 for teh cat back

I've got a twin 2-1/4" system on my VY ecotec (sure different motor but, meh. Exhaust off an 'SS' with the rear resi swapped out for 2-1/2" pipes).
That, IMO sounds a hellova lot better than 99% of the available 2-1/2" catback systems out there.
Had a redback cat back that sounded woeful, tinny, computerised and droney to the max. On my previous car, VT.
ok guys jsut wonderoing how loud will the twin 2.5 twin 2.25 and single 2.5 be compared to each other i want somting with a good mount of noise but not overly to loud that it will wake the whole neibohood up jsut my street maybe lol

why is it so hard to chose an exhaust grr and with the muffles get intermediate and rear or jsut intermediate
