I love it, 2011 Duramax

At first I had the MBRP 30 inch quiet tone 4" muffler, I thought it sounded good. Then I installed this shorter muffler and the sound level decreased a tad but has a very mellow gurgle. More throttle response and more mid torque and increased gas mileage and more power in my Eco-Tune. You will feel every throttle movement. Very mellow and quiet around cruzing speeds. Sounds like FlowMaster 3 or 4 chamber. If you want not so loud and mellow tone........ Buy Now. Thanks

I put this bad boy on a 96 f250 with the 7.3 stroker. got an 8 inch stack system, didn't even replace the down pipe and I got nothing but raw power, and an absolutely gorgeous noice. On those ol 7.3's you can hear the turbo at all, until you put this muffler on there. now you can actually tell that there is a turbo!!! spools just above idle now!!!! there is not a problem in the world with this beauty!!

I was hoping for a quieter muffler than my magnaflow. On my 02 Duramax with magnaflow 4" exhaust this muffler was louder than the magnaflow glasspack muffler. No noticable HP change, no better mpg, no drop in egt... only louder. Loud pipes do not save lives, they just annoy everybody else.
