V & H stainless hi output duals
So I got my bike back from the dyno...seems I don't have enough backpressure..bottom end power suffered big time.. Anyone know of a way to increase backpressure? Really don't want to have to replace my new exhaust system..

Check your cam power band. Might be the curve of the cam and not the exhaust.

I have put Super Savers on my SG and can feel the difference over the HO's. Most people don't have the motor to run big dumps. But looks overrule performance.
Sell them on forums try monster rounds? I do have a set of baffles that help, cheap if you want to try them.

My build is noted on my sig. When looking for an exhaust I talked to Drago, Fuel Moto, and Vance and Hines and the consensus was no baffle larger than 2". Your high output pipes are meant for a build even more radical than mine. A lot of pipes have big baffles (2.5+) that sound great and work as long as you have a cat to produce the back pressure. I really wanted Cobra 4.5's because they sound great, but I backed off because of the 3" baffle.
