hey everyone, i drive a VY S II and im wanting to do a full exhaust upgrade eventualy. i want to replace headers, pipes and muffler. was just asking if i should be getting a 2.5" system (most people see to go for this) or a 2.25" system?? i wont be doing to many mods to the engine, just intake probably.
the real question is i have heard that for a stock V6 ecotech, 2.25" pipes are better for the engine over 2.5" pipes? something to do with back pressure or something?? any help would be great =]
thanks everyone,
sam
p.s any sugestions about exhaust system would also be appreciated, let me know what exhaust you are running if you have upgraded =]
