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.
