Flowmaster 70 for Toyota Tundra 2007

Reviewed By David P (Galveston, TX) Reviewed for a 2007 GMC Envoy —1/23/2008 2:08 PM

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.

On 2013 Dodge Durango Pentastar V6

Reviewed By CLYDE T (Tarpon Springs, FL) Reviewed for a 2013 Dodge Durango —8/31/2013 6:50 AM

Place the 40's on my Durango V6 and the sound is amasing. The sound is louder and deeper than the stock mufflers with just a little modifying of the hangers. Not quite like a Hemi, but it makes heads turn.
