I have a pump gas BB Duster that I built just to drive, no racing. I had Flowtech Raptor mufflers on it, sounded good but they were junk, lasted a few months and rattled.

I wanted Dynomax Super Turbo's but after reading alot about how they tend to rust, and the 3" version bottleneck's down to 2.5" inside the muffler, I decided against them.

I read about a muffler test that clearly showed the stainless Borla XS muffler as the quietest at idle and WOT than most of the performance mufflers. So tonight I spent the extra coin on them and all I can say is they are not what I was looking for, they're louder than what I wanted.

I'm thinking of taking them back off the car in the morning and getting something else but I don't know what? I won't have an X-pipe on this car til next year, might do an H-pipe next week, my pipes are 3", no tailpipes either. All this stuff would help but money is tight and spare time is even tighter.
I'm thinking of putting the Super Turbo's on and seeing how long they last?..
