I have had a set of 09 supertrapp stouts for months. When I 1st got them I liked them. Now they started sounding bad. I am not happy with them. I have owned supertrapp pipes before and liked them.
CAn't stand how they make my head hurt from the sound they put out.
Called supertrapp and they will do nothin unless you want to spend more money.
Good money throwed away.

 

Totally! I bought a truck once from Ford, really liked it at first, I thought the stereo was great, but then after a few months I realized it wasn't quiet as good as I thought, and I'll be dammed if Ford wouldn't do anything for me unless I spent more money....

Get real...

 

That sucks. I've got 700 miles on mine now, they still sound great. Maybe you have something else going on, loose clamp or ????

I've had the non-catalytic Supertrapp 4" Stouts on my RK for about 1200 miles... They still sound good and I picked up 4 more mpg's with them with combo city/hwy riding to 47 mpg...

On an earlier reply, someone stated that they had more pressure on the right than the left,,,if you're not running a True Dual pipe,,,that would be correct.
