I asked this in a different thread, but this may be the place to ask it as well,
Does the crossover leave more low end torque than the true duals or can you not tell the difference? There is a bike at the local stealership that has a vance/hines header with Rinehart slip ons that sounds great, but it has no ***** in 5th at 65mph (it sounded like it was midway in the RPM as there is no TACH.) It's like the machine runs out of steam on the highway. So, I don't want to loose any more torque if you catch my drift.
I put Rinehart true duals on my bike this year and they are killer! They do have a different sound than the Rinehart slip ons with stock head pipes. Great sounding idle, but surprisingly quiet at cruise.
Will changing to Dresser Duals and keeping stock mufflers reduce heat?
I would say yes, but not 100% sure as I believe most of the heat is dissapated through the head pipes but if I were to add head pipes I would trash the stock mufflers.
Will remapping be sufficient or is it necessary to install a management system?
You only have to remap if you change the air cleaner, I believe a pipe/muffler change only don't require an ECM change or a fuel management system.
I have installed the Rinehart true duals on my 2010 Street Glide. Sound and performance is unbelievable. I'd highly recomend these pipes to anyone. Only issue is the pipe off of the rear cylinder runs right over top of oil cap and trans screw. Does anyone have a solution for checking/changing fluids with this setup? It's not a huge deal, but something to think about as I hate getting burned.
The true duals with the stepped headers will perform better than the straight 1 3/4" headers. When I pulled my y-pipe earlier this year for the fullsac conversion, I felt like I had lost a little off the low end. When I pulled that system off and went to Rinehart TDs, I hot it all back and more.
