I'm looking for a new exhaust and keep all 4 stock cats. I've been looking at and comparing systems. And some people say glasspacks sound nice but I don't know what size is best. Any recommendations?

 

I got the dynomax bullet 2.5" in and out. not technically a glass pack but I love how it sounds and it is a cheap temporary solution until I save enough to go true duel with better cats. I just cut out the muffler, bought an extension tailpipe piece from part store and clamped it in. about $50 in all. will weld it once I decide on if I want it before or after the rear tire
