I got a smoking deal on a set of 4" Jackpot slash up slip ons and got them installed in about 1.5 hours. I was actually surprised how easy the install was on a 3 year old bike with 13k miles. At idle the bike sounds great and when the throttle is cracked it sounds even better. I hate the fact that I cannot hear the bike when on the throttle under load. While riding it the sound doesn't sound real deep but I think the sound from the seat is significantly different than it is behind the bike. The quality of these pipes is outstanding. Made in the USA and they look fantastic poking out from the rear of my King.

I'm going to have a set of the 3.5" available in about a week if anyone is interested PM me.

 

I've got a couple thousand miles on mine. They aren't going to set off any alarms but I think they sound pretty good for the cost and after a few hundred miles seemed to get a little better sound. Still not as deep as some Ovals and others I've heard but works for me.

 

Riding home last evening from a 300+ mile trip I was thinking how good these pipes sound and that now with about 2000 miles on them they seem to be just a little louder from what I remember they sounded like when first installed.

 

Love mine too, have a pair on each bike!

 

I love my 4" Jackpots. It's the best money I spent on my RK.

 

Mine are great! I think they are the "best" sounding slip ons out there.

 

Love mine as well, interesting thoughts. Mine really wake up under load and throttle.

Any other mods yet? air cleaner, heads, tune of some sort?

 

My pipes wake up under load nicely...even on cruise control when it comes to an incline you can hear the difference in the tone produced.
