I might be selling my APR one soon, going to a 3inch one
MODS- TOO MANY
Mine is turbo - where cat was - 3"
from cat to the rear resonator which is deleted is 2.5"
then from to muffler 2.25"
I could go 2.5" all the way, but at the moment my car feels great with enough torque lower down, and great power higher up.
With REVO - the boost peaks at 25psi then slowly tails off at higher RPM.
Oh yeah - I have removed my cat 2 weeks ago - yes it is a little smelly, but sounds awesome with stock muffler and goes like stink. And no - it's not illegal in NZ currently.
06 Polo GTI - REVO Stage 2 = 140kw @ wheels.
06 Golf GTI - Bluefin Stage 1 blacked out with ED30 theme, leather, xenon, etc.
I'm running on custom 2.5" catless downpipe fabricated by my local exhaust shop. In order to avoid CEL, my mechanic did fabricated an 'extension' so that the secondary o2 sensor placed an inch higher than original position. And of course a lot cheaper too![]()
