flowmasters
Anyway, my new 40 series sounds great but it is giving off an odor... I guess it needs to burn off some kind of factory coating or something.
When I installed my longtubes I put a cat with a built-in h-pipe in and dual flowmaster knockoffs (don't remember which brand) and dumped under the bed...sounds perfect IMO. Throaty when I romp on it and pretty quiet around town. Still has that Flowmaster drone though.
Nice clean truck.
