thunderheaders
Can anyone please tell me if TH are way louder than rush 1.75's? I have read about their legendary performance which is really key, But I don't want anything abnoxiously loud.

+1 Ratt. I don't think I've ever heard Rush 1.75s in person to compare. TH at idle and normal cruising speed isn't bad. It's when you crack that throttle that people know you're comin.

I had the 1.75 rush slipons. The thunderheader is not any more loud. I have a fatcat 2-1 and it is more quiet than the rush too.
I think the fatbobs look better with the D&D fatcat. Check out centerline's bike and you'll see what I mean. The D&D performance is top notch(equal or better than thunderheader on a stage1 bike). Either system will give you a nice improvement in torque over your current system.

one more question is there an actual baffle in the pipe? I mean the rush have baffles , butthere is nothing to block a wire test.if a cop slides a wire into the rush there is absoloutely nothing stopping it,no back wall to speak of.when i got the rush you could look right through like a telescope!

Absolutely. I was runnin SEII's 2-2 before. You definitely get about a 10%+ boost in performance. Not bad for bolt on. I also like the fatcat. Basically, going to a 2-1 will give you better performance. Some more than others.
