Flowmaster Super 40 Series Mufflers Reviews

2005 Pontiac GTO 6 Speed

These Super 40's really woke the car up. Very noticeable gain in acceleration. I also had my muffler shop install an X-Pipe and wow did this pairing wake this GTO up. Spent half of what a cat back system would of cost.

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.
