I did a bit of searching and couldn't find much about this topic - so i shall ask.

 

I have an 88 GL Turbo and eventually want to re-route the exhaust as i am lifting the car, and i want to upgrade the exhaust.  When i do this, i want to put a high flow cat and possibly a magna flow muffler.  I also plan to bump up to 2.25" or 2.5" pipe. 

 

Has anyone out there upgraded the exhaust on an EA82T?  What did you use?  Pipe diameter?? - this is my main concern as i know a high flow cat is a high flow cat, and mufflers are pretty much a preference for sound etc.  Any suggestions would be stellar.  My goal is to boost performance a bit and to make that little EA82T boxer sound good.  Cheers

Used 2.25 on my 90 turbo wagon. Went with that size because when I cut the flange at the turbo off, 2.25 size pipe was a perfect fit. Muffler used was a straight through turbo design. Noise was minimal, actually very quite. 

TWE header, td04, modified 3" wrx down pipe, 3" catback with a 18" resonator, no cat or muffler

 

Crazy loud and would never pass an emissions test.
