So long as people recognize this thread is in a Tech Forum and not OT, it shouldn't turn to crap.

But going back to XwChriswX's question...I don't see why going with the bigger exhaust now would be cause for concern, unless it it involves a noise/volume issue. In that case, I haven’t heard much about the noise-levels of GTM's 3" exhaust vs. other options.
