Well I've had a Borla XR-1 oval and then the Dynomax ultra- flo welded muffler on the truck since I've had it. Both sound vicious and performed well but me being old school- I grew up with everyone running flowmasters. Anyway I've always loved the tone so I Decided to out one on my truck for a change. After a little debating I went with the super 44 3" and man does it sound mean. Kind of surprised because it has no more interior resonance than the other two mufflers. Anyway thought I'd share. If I knew how to I'd do a sound clip. And yes I still have the other two mufflers because I know I'll change out again!! LOL. I'm never satisfied.
