Flowmaster Street Performance Mufflers Reviews


Sounds great!!!!! 40 series

Reviewed By charles t (FOUR OAKS, NC) Reviewed for a 2014 GMC Sierra —4/15/2015 8:59 AM

Muffler sounds great when added with a k&n 77 air intake. Just remember new sierras and silverados, need to have the exhaust adaptive valve locked in full open position for full effect. Spring loaded valve damper inside pipe 6 inches after factory muffler. There to keep down sound when in v4. Does not effect performance of vehicle. Also remove the resonator. Worth the investment!!!!

Not real loud

Reviewed By Paula C (SAN ANTONIO, TX) Reviewed for a 2008 Toyota Tacoma —2/6/2015 11:41 PM

It offers a great low rumble when accelerating, but nothing to over the top. The more you drive the more you break it in.
