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.

So far so good. Purchased as a surprise for my husband delivery was quick, installation was easy done at a local muffler shop. He was quite surprised when I picked him up and had him drive she has just enough sound to take notice but not be overwhelmed.
