I'm going to put a different 2-1 exhaust on my bike.
Currently I'm looking at Bassini, Rush, Reinhardt's and a few others.

Any pros - cons about any of them??

I was thinking thunderheader but I'm not a big fan of a company without customer service.

 

I really like my Bassani RR, I really felt the low end better than the Rb pipe. Nice sound, not real loud especially at cruising but very noticeable when you open the throttle...

 

Thunderheader's Work
Others are 2 into 1...Most Loud.
I have heard good things about R&B Racing 2 into 1, but...I have nothing but "I like it" to go by...There are a Few R&B at the Track...I will Make it a Point to see how they perform...
Know that in the "old days" the Thunderheader was the only Pipe that made more Power across the board than the Stock cross-over staggered duals with free flowing Mufflers...
That was some time ago tho....

 

i have a kerker with a removable baffle that we tuned so its as good as any

 

I've had T-H, Cobra,V+H pro pipe, B+C style RBR pipes on my Evo. By far seat of the pants the B style RBR out performed all of them. I run all the above on my Twin Cam with the same results. The Train had dyno results on all but the Cobra which sucked on both bikes. the D+D fatcat has made good power on a friends Fatboy that has similar mods as my Train. Hard choice for you.

 

I put a thunderheader on last summer, havent had any problems with it, so am not sure about their customer service. also dont think they're as loud as everyone says. they'll bark when you want em to, but pretty tame when just cruising. (my opinion) some people say the end of the pipe ugly, makes me like it even more!

 

I have Pro-pipes 2 into 1 and it's great. Also, try D&D (in Fort Worth). They have good sound and power.

 

RBR????
I'm not familiar with those.

 

I tried them a couple of years ago.
No matter what I did the rear pipe hit my cam chest.
I called D&D and asked for help and followed all their suggestions to no avail.
I got them to send me a different set of headers same result.

They tried to claim it was my fault for putting an aftermarket cam chest on (it's stock).
I don't have a lot of use for someone who blames me for their faults.

 

R&B Racing...the Only one I would consider If I didn't choose the Thunderheader..
But, I am Biased by Performance
