I found a good deal on this exhaust, and was wondering if it'd choke up the flow too much, or still be ok...I got mixed answers in my last thread about 60mm in general, now I'm asking about this specific exhaust. Thanks for the help

 

the ws is too restrictive for turbo applications.

 

I made 256 (bseries) with this catback with the cat still intacted... but if you ever want to go higher in hp you will not want to this exhaust... get a magnaflow 3" straight through design that comes with the kteller kits.... i like how mine sounds.... lol... peace

 

i wanted to upgrade from the stock gsr muffler so i tried the 60mm on my turbo dc2 with 3" piping, no cat....


...it felt worse then my stock muffler

...but it was a little louder
