what exhaust is the best at teh moment I got 2.5'' turbo elbows but the rest of the exhaust a just s 2'' SO I am thinking to 2.5'' inch for better exhaust flow. what should I do 2.5'' ?

Yes your right u want 2.5" -3" as turbos prefur flow unlike N/A's that rely on back pressure!

Mine has japspeed de cats & katimoto rear boxes with no baffles ;) can't get much free flowing than that & it sounds awesome ;)

I found a good garage they are exhaust specialists so I ask them to make my pipes from turbo elbows to all the way to back boxes. I they ask me for £220. so I think thats quit good offer.

2.5" would be more than adequate. 3" would probably do all 6 cylinders just fine on an unmodded engine.

what do you mean by power flow?

I got now 2'' inches pipes so that is to small yeah or is ok?

They are a custom exhaust system they are fitted in lots of garages around the country

2" is too small on a turbo u will be restricting the flow

I will tell you what results I will get on Friday. Is could be any increase of bhp with 2.5'' exhaust?

Yes free flow is the key so a good induction kit(apexi/K&N ) etc decats & 2.5 or 3" bore exhaust will free up some horses ;)
