I finally broke down and ordered a muffler elimination kit from Geno's. Call me careless, but I eyeballed the fit and cut the muffler out with my sawzall. When I tried to put the new pipe in place, I realized that it's about 3 inches too short #@$%! Has anyone else made this dumb mistake? Are there any 4 inch pipe adapters out there? Places like Advance and AutoZone don't carry any pipe that large? Thanks
