Exhaust a bit too loud

[brutpwr]

Maybe run it out back to behind the rear tires on the sides. One additional bend instead of straight out the back is probably worth almost an additional decibal of noise damping. If its more like stock levels you r after then switch out the tailpipes to 2" tubing behind the Magnaflow.

Just directing the noise there is elsewhere is worth a ton in perceived noise level's. I would put a tail pipe on it before I swapped muffler's again lol.

I had the same issue with my Flowmaster 70 Series Big Block. I thought it would be cool to dump it right out of the muffler. Well, the resonance in the cab was overwhelming so I installed the tailpipes that came with the kit. It reduced the loudness and the resonance considerably.

Chambered mufflers drone. Tailpipe will help but it won't cure the whole problem.

If it would have been one in two out I would buy from you but not good luck.
