you wont be beating anything witha  3.5 inch exhaust haha ur turbo will be spooling al day with no back pressure to be able to push the car mate haha 2.5inch turbo back resonated and ull see good results

3.5" the tip of the exhaust!  .. the pipework  will be 2.5" yes the exhaust man recomended that too

pray tell how a larger pipe AFTER the turbo will affect it's spool.. when the manifold, and therefore "back pressure"  before the turbo.. where the spooling force comes from, is left unchanged

I don't mean to sound like a miserable c*nt but this whole back pressure myth (created by honda owners i believe) really bugs me... exhaust pulsing and gas velocity really isn't that hard to get your head around if you know the basic workings of a 4 stroke motor.

system made
if i am getting a cat back what size do you think i should do the pipework??

[topher]

won't make much difference performance-wise as long as you don't go smaller than the outlet of the cat.. anything bigger than that is just added noise and weight (and more chance of banging as it goes over the rear beam)

[navmk4gti]

hmm what is it standard then?? 2.5" sounds ok then.. dont want it to be that load jus nice deep tone .. im mainly doing it for the looks
