I have a friend just bought a 2003 Ultra Classic. He wants to know what people feel is the best performance exhaust. He wants true duals. I have Rineharts and like them. But what do people think is the best. Not worried as much about price as performance.

Thanks

 

D&D 2 into 1 with a ghost pipe.

 

YEP! thats what I'm getting on my 2001 Ultra and as far as performance (from what I have investigated) they are #1 .

 

The D&D mentioned is supposed to perform very well but I like the sound of my Thunderheader better. To me it sounds throatier and deeper than the Fatcat. They both perform good and both are available with a ghostpipe.

 

If he wants the true duals and is pretty much doing a stage 1, SuperTrapp SE's put out some pretty good numbers. Plus sound good.

 

No one best exhaust. The performance of any exhaust is gonna be dependant on the tune. Fatcat, V&H Propipe, Rinehart TDs, Bub 7s all work well. Geberally speaking, a good 2-1 will enhance low rpm torque, and a good TD system will return higher peak numbers.

 

The 2-1 may give you better performance but, will never sound like true duals, IMO. I have the Rinehart TD's also from when they were built by Bub with the steped header design and feel they perform well! Not sure how the new design/build quality is though.

 

Not sure about dyno test results (which would also depend on Air intake and Ecm remap or piggyback add on ) but I tend to like all the Vance & Hines products.
I run the Big Shots Staggered Black version. They sound awesome.
They came on my bike when I bought it, but I think they run around $650 or up for price. I have the old SE dealer map download and the SE air intake.
Runs pretty good but saving for a TTS mastertune.

 

Exactly...and this could be argued all day. I use V&Hs on all my bikes just cuz. They get me down the road just fine and sound just fine and they look just fine. If there's a difference between my well tuned bike and another it would be so little a difference that I wouldn't notice it.

 

for my application, it's gotta be the v&h 2 into 1 pro pipe. i've had several different types of exhausts on my past few harleys, but the current v&h pro pipe has to be the best i've had. great performance and the sound is incredibly sweeeet.
