Flowmaster 50 Series Big Block Mufflers Reviews


It's quiet, but robs power

Reviewed By Jesse A (NORTON, VA) Reviewed for a 2004 GMC Sierra —7/11/2019 6:36 AM

. Certainly made the exhaust quiet, the engine makes most the noise now. Doesn't really have a "tone" over stock muffler. About the same as I can tell. I had the stock 3.5" with a test pipe on it and edge juice. You touch the throttle and it was taking off. This muffler is HUGELY restrictive compared to a test pipe or even straight through 4". Really have to step on it to get it to move now. To do again, I'd buy a 4" system w/muffler and be done with it.

Flowmaster 70- 2014 GMC Sierra

Reviewed By Ruben G (WESLACO, TX) Reviewed for a 2014 GMC Sierra —5/13/2019 8:22 PM

These mufflers are perfect. Not to loud or crazy drone. Quiet while cruising and moderate roar when you open up the throttle.
