I gutted my stock can and cut it down to just after the rear mount... Sound is pretty "tinny" and I can def feel a loss of power from 2-4k but up top it is noticeably better. Anyone know what the other dudes were doing inside there mufflers? Baffles or just a pipe with muffler pack? I see that one of em put up pics of the inside but now they are gone. Being a welder/fabricator I'm not sure what the big mysterious secret is about what people do to these mufflers. It cant be that scientific.
