I heard from a reliable source a few months ago that Bub's was no longer going to manufacture them.
This is true They stopped at the end of last year I believe. I know someone is making them now, but I do not know who.
To the OP, I can only speak for my Rinehart's and tell you I like them a lot in both sound and performance. I am not all that familiar with jackpots though
If you are just doing slip on's, whatever. If you were doing a full system I would say Rinehart for sure. I don't have any first hand experience with Jackpot slip ons but read a lot of good stuff about them.
+1 Make sure the Rinehart sound you like is coming from slip ons, as they don't sound the same as the true duals.
I have the jackpot headpipe and the slip ons and couldn't be happier, if I was going true dual I might have looked at the rhineharts. The price is right on the jackpots too.
I've got rineharts on my 09 RKC and Jackpots on my 09 Ultra so I can certainly compare the two. I got the Ultra for 2-up and the RKC just for me. The rineharts are a bit louder and the sound is more pronounced. The jackpots are mellower, but not much, still a deep sound. No problems hearing the tunes or the wife over the jackpots. Both of them have a nice rumble when flying down the road but crack them open and the sound is great.
Personnally, I put the rineharts on the RKC more for the looks than anything else. I LOVE the eagle beaks. If i weren't for the looks thing, I'd have jackpots on both.
Not 100% sure, but I think Rinehart went in with Custom Chrome. After talking with Jamie at FuelMoto and looking at his charts where he tested different pipes, I chose the Jackpots! Glad I did! The quality and sound are the best I've had yet.
