The answer is Yes they are, one of the deepest sounding out there, slip on or true dual. Two of us at the dealer I work at(car dealer) are riding Roadkings with the slip ons and they are deep and when you give it gas, they can bark quite nicely.

 

Rich... how do they sound in comparison to Rush slip-ons?

 

I don't know, sorry. I choose mine after hanging out at the dealers on a Saturday, and I liked the Rinehart. I didn't go with the duals, not knowing there maybe a difference in the sound, and all and all, there isn't much difference, but my hearing isn't what it use to be either, so..........

 

Cheers!

 

I have the Rhinehardt slips on and they sound pretty good, I just added the Tru duals and even better.
However, if Iwas to do it all over again (which I might), I might just go with the Bassani system. I just sold a set to a friend of mine and am I'm kind of jealous. They real have a noticeable sound difference.

 

I have the RinehartEagle Beak slip-on's on a 2006 Street Glide. They sound good,they rumble,but definitely not as loudand deep as the RH true duals.

When installed, they were combined with Stage I air cleaner mod and the Screaming Eagle Race Tuner, along with some dynomometer time. Results were real nice - at just over 79 hp and 80 fp torqueat peak from the 88 inch motor - so they seem to be a little better for making power than some of the others.

A word about the slick Rinehart black end tips: mine turned purple. More on the right pipe. You can either switch them so they equal out or use a heat resistant spray paint to solve that issue.

 

I've heard that a bit about those end caps... not cool!
