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.

Flowmaster 50 Series Delta Flow Mufflers Reviews


Exactly what I expected

Reviewed By David V (MANLIUS, NY) Reviewed for a 2000 Jeep Grand Cherokee —4/17/2018 2:37 AM

Flowmaster mufflers have always been quality, but most often more than I wanted to spend. When I finally bit the bullet and bought one, it exceeded my expectations. It has a nice deep rumble that is not overly loud or offensive but about as loud as I want it to be. Sounds perfect for my straight 6 cylinder jeep.
