Hi again,

Don't know if anyone remembers me or not, but I'm back on here; still got the GXP. Took it to the track and ran [email protected] and was disappointed, even though it was 89*F at the time and everyone was running crap times. So I've modified my factory intake to flow better, and have come back here to see what I can find as far as Cat-Back exhaust systems go.

Is the GT-R the only aftermarket option out there, or is there a dual muffler design out there, how uch better will the magnaflow flow versus the stock GXP cat-back system?
