I'm doing my cat back this week and after listening to some exhausts on YouTube I'm still not sold.. I want a DEEP sound and I was thinking a thrush glasspack and magnaflow mufflers but maybe even just the glasspacks with no muffler.. It's on a 2000 gtp with headers 3" down with no cat so I'm thinking it may be to loud and raspy with just the thrush glasspack.. Any suggestions would be great, thanks
