Yesterday my muffler and cat fell off!! :-laf I examined my cat and found there was smithing blocking it! :-laf After some probing, I manage to get it cleaned out. Installed it and made a muffler delete pipe. Took it out for a spin, WOW!!!! What a difference!!!! Turbo spools up real nice!!! Left over a 75' of rubber until I let off. Can't wait to see if it helps my mpg. Resonates something terrible though. New Flowmaster chambered muffler will be here in a week or so.
