this flowmaster sound great and the sound is not that loud/perfect just the right tone.

Great sound with little to no resonance inside cab. Had a muffler included with the JBA exhaust system and it was junk. Stainless steel, but just a big glass pack. The resonance inside cab was horrible. The 70 series sounds good on the outside without the resonance inside the cab.

The sound is awesome, mellow at idle with an aggressive growling rumble on acceleration that mellows out again at cruising speed. I would leave the stock resonator in because there is a slight 1700-2000 rpm drone if you don't. The truck gets plenty of compliments on the sound and has more low end torque.
