On my 2003 Blobeye STi with PPP, the existing centre section - what's the diameter? Is it 2.5" or 3"?
As i understand it it's currently resonated and a straight through pipe is a cheap way for a bit more noise and a very slight if any bhp increase?
Do i need to look out for a 2.5" centre non-resonated pipe? as ive seen 3" ones about but surely that would require some work to mate with the backbox pipe and the de-cat pipe thats at other end.

Ive seen ones from TSL, H&S and apparently Milltek do them also but havent found that one yet.
