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!!!!

Flowmaster Super 10 Series Mufflers Reviews


Perfect muffler for my truck

Reviewed By brian e (Columbus, OH) Reviewed for a 2002 GMC Sierra —4/12/2015 5:09 AM

I had a 40 series flowmaster single in/out with stock tailpipe on my GMC 5.3, it sounded good at idle but disappeared at WOT when I really wanted to hear it, so I bought the super 10 to replace it, I dumped it right by the rear axle, this thing sounds amazing, exactly what I was looking for, I find myself flooring the gas peddle just to hear that amazing exhaust rumble. I couldn't be happier and if you are scared it will be too loud, don't be, it isn't super loud, but it is deep/aggressive.

Flowmaster Exhaust

Reviewed By Bill W (Charleston, SC) Reviewed for a 2015 GMC Sierra —4/7/2015 6:11 AM

In my opinion, this was a great purchase! I had been fighting the decision for months since i bought my 2015 GMC Sierra, do i or don't i install and exhaust system? Well i finally decide yes, and boy am i satisfied with the sound! It was just the part i was missing. With a helper, i installed the entire system in my driveway in less than an hour and a half! Very easy, but it probably helped that my truck has a 6" lift on it! The sound is deep and just what i wanted, and the look is perfect
