The Thunder performance slipon are made my Supertrapp/Kerker and are the same body as the Supertrapp se series. They have a different baffle but the baffles are interchangeable. I just changed the baffles in mine and sound much better.

 

Used to be Cycle Shack, but that was 10 years ago.

 

Dad (aka Motorcyclelockman),
You really need to find some new baffles. Your Harley is sounding more like a Goldwing. I have an 03 Wide Glide with staights on it and when they are sitting next to each other you can hardly hear yours. And then when I actually crank mine you cant hear yours at all. HAHAHA!!!

Love ya Pops,
Your one and only Baby Boy

p.s. It actually sounds really good its just not loud. But your kids are always gonna mess with ya any time they get the chance! And always remember... Be nice to your kids. They will chose your nursing home.

 

HA HA HA I hear ya.

 

cycle shack made them for harley, and later on went to supertrap, i couldn't even guess who's making them for harley now though. i know i really like my v&h pro pipe, so no more s.e. pipes for me.
