OK OK probably a little late for this now, as I just picked up a set of Bub 7 true duals last night for a good price. But wondering... do the head pipes on these use a non-standard size like the Rhineharts do, where a standard slip-on won't fit? I know only Rhinehart mufflers will fit Rhinehart pipes, was hoping the Bub 7's were a little more standard if I wanted to change the mufflers sometime down the road.

 

I started to answer yes but if I remember they open up to 2" in the muffler, see if your stock muffler will slip on, that will tell the tell, I had them and they are a awesome pipe with the bub7 mufflers.

 

cool thanks for the info... they should be here in a week or so, will check them... I've heard nothing but positive things on these pipes, I'm looking forward to getting them on.

 

Installed Bub 7's true duals on my bike and love them. Not sure what the diameter is on the head pipes/ mufflers. I'll have to chaeck when I get home.

 

When I was shopping for true duals for my 09 Ultra, I called BUB and the sales rep told me they come in 1 3/4" and 2" diameter. You might want to check which size you've bought.
By the way, I ended up buying a set of V&H Dresser Duals and I'm extremely pleased with the results.

 

my guess is that the slip-ons for the stock headpipes are 1 3/4", and the complete system is 2" like the Rhineharts are/were... o well np, I got such a smokin deal on these, and 99.999999% I am gonna like them that it won't be an issue.

 

Don't know if this will help or not, but I have a set of Bub 7 slip-ons that fit perfectly with the stock head pipes. But, I don't know if the Bub 7 slip-ons with the true dual system are different diameter than stock.

 

BUB sells their true-duals both as a complete exhaust and as headers only. The part # for the headers for my 09 was 05-3023CG. That's the one the rep told me they come in 1 3/4" and 2".
By the way, before switching to CFRs, I had Rinehart slip-ons on my Ultra and they were 1 3/4".
