i just ordered one, and it is shipping........ i will let you know when i get it

 

So the test pipe... can hook right up to a stock exhaust system???

 

words of wisdom, my 1+ flash bored me in a few days.... only good thing is i dont lose to minivans anymore....

 

All the test pipes on Ebay are 2.5inch I hear we should not go with the 2.5and instead go with the 3inchaccording to this company:

"The Evolution Racewerks Test Pipe's 3" to 2.5" design is superior over other test pipes that are 2.5" in diameter from inlet to outlet because the 2.5" test pipes will have a "step" right at the outlet. Since the OEM K03/K04 turbos have a turbine (exhaust) outlet of almost 3", the flange of the 2.5" test pipes will actually make a "step" right at the turbo outlet. This step acts like a wall against exhaust flow and when the exhaust hits it, major exhaust turbulence is created, at the worst spot possible, right at the outlet of the turbo. If you have a 2.5" test pipe, check it out. Look at the inlet flange and you will see a "ring" of carbon deposits on the flange. This is the "step" that the exhaust flow is hitting."

 

interesting info, i guess i'll be getting test pipe for xmas, probably 3">2.5" if its true about step, going to ebay to check it out
