Ozzy Member 40 Member For: 15y 1m 18d Gender: Male Posted 19/10/09 10:10 AM Share Posted 19/10/09 10:10 AM when does your power come on, a good exhaust will flow low down power to get you started and then mid to top end to keep you going, depends where you want you power 3.5" twin dump pipe /3.5" system good low down power less lag (I would recommend this for mid 300rwkw)4" dump/3.5" or dual 2.5" system (xforce stainless) good top end power more lag and more back psi (I wouldn't recommend )Back pressure is not wanted on a turbo charged engine. Its hard to get top end power and more back pressure from a system that will flow 1000Hp. Cant be too bad, lots of people use the system. But Ill before I get started. hey guys im in the process of playing of numerous exhaust shops... so far quoted 3.5" split n single system for $1300 mild steel4" dump n 3.5" single system for $1400 mild steel4" dump stainless with 100cpi stainless cat into twin 2.5" system for $1400 mild steel all fitted... Good stuff. Either way youll be happy with it. Get the one you want. Your car, your coins. Link to comment Share on other sites More sharing options...

Ozzy Member 40 Member For: 15y 1m 18d Gender: Male Posted 20/10/09 10:42 AM Share Posted 20/10/09 10:42 AM One should always take into account the exhaust gases cooling as they pass through the exhaust system and the need to maintain exhaust gas speed.

I will be geting a tune in the nex wk or 2... Link to comment Share on other sites More sharing options...
