okay so i have a rs and i'm getting a apex n1 3" catback..okay so what should i get for a test pipe and how will i go from a 3" exhaust to a 2.25" downpipe? i'll be putting a turbo on in the spring..
thanks

You could buy a 2.25" testpipe because most 3" catback will come with a transition or adapter piece (2.25"-3") that will allow you to bolt it to a stock exhaust.

so if it comes with an adapter for 2.25"-3" couldnt i just put that on the test pipe-downpipe connection? i want to get 3" straight from front to back

No, because the cat-conv. flange is not aligned--the flange on downpipe end is turned--unless, you buy a straight pipe with a swivel flange.

damn it..so i pretty much have to get a 2.25" test pipe?
i mean..i'm going to be getting a turbo soon and the kit comes with a downpipe right? isn't it 3"?

You could probably get away with the 2.5 inch testpipe.

I have the 2.5 inch on mine with the stock downpipe GS-T catback(2.25). It fits ok. The 2.5 will fit to the stock downpipe, just not sure about the 3 inch catback.
