Magnaflow Performance Mufflers Reviews

Exactly what I was looking for!

Reviewed By Jeremy S (SOUTHAVEN, MS) Reviewed for a 2015 GMC Sierra —3/5/2018 8:28 PM

The newer GM trucks have a lot going on with the exhaust, keeping them quiet as can be. I wanted to be able to hear the v8 without it being obnoxious, loud or having a drone at highway speeds. The 22" Magnaflow muffler is perfect, gives a nice deep tone and you can't really tell it's on there until you step on it. Very pleased with the purchase!

Flowmaster 50 Series Delta Flow Mufflers Reviews

Welder fabricater

Reviewed By Andrew M (High Rolls Mountain Park, NM) Reviewed for a 2008 Jeep Grand Cherokee —12/26/2017 7:36 AM

The muffler arrived with one side scraped up which wasn't a concern for me. Installation was easy. Just make sure you have clearance where the tail pipe bends next to where the spare tire heat shield is located. I had to cut and reposition the rear hangar to move the pipe over about an inch. The 50 series is quiet and slightly louder then the stock muffler. I was told by the sales person that the 40 series was ubnoctously loud and I should get the 50 series. I should have gone with the 40.
