x pipe question

[Leo0916]

im changing my bbk x pipe out to a Magnaflow.. off road or with cats??

I would say go with cats and it will sound better, smog, and have no real power loss unless you're making over 500 hp.

I plan on putting a whipple 3.4 on in the future, i have a magnaflow cat back on it also..

If you don't have to worry about emmissions I say o/r. Much cheaper, I think it sounds better, and you're gonna be doing a twin screw eventually anyway so you'll be well over 500 hp.
