I really didn't want to post another LT header post... But I can't seem to find and 'sound difference' posts with enough detailed information to go off of.

I have a 2012 GTCS, I currently have a bassani O/R X pipe and full 3in catback system. Of course ... it's not loud enough :grin:
Part# 5011R5 Bassani Exhaust - Bassani.com (this one)

I've been doing a bit of research and according to many forums and posts the 1 3/4 are better for N/A Coyote...

LT 1 3/4 and 1 7/8 sound difference/comparisons ?
