Looking to buy new muffler but I need to know how the stock is set up. Is it center/center... offset/offset... something else. Anyone?

 

I've been looking into buying a new exhaust system myself. So far the best I have found and it was also higly recomended is the Skunk2 Mega Power Exhaust. www.skunk2.com Might want to check that out, they also shoe dyno tests on there site, before and after.
