Is it worth it to add pipes?

Last year I purchased a pair of V&H , longshots for my Sabre. I also picked up the v&h quiet baffle for the pipes. I was planning on using flat, stove gasket rope in lieu of the fiberglass wrap. My question is to those who have performed the switch on an 1100. I want to improve the responsiveness of the throttle and overall performance. Did you find the noise to be excessive? I just want tohear some feedback before Iinstall the pipes, rejet the carbs and add a k&n air filter. The dtock and v&h pipes are both in very good condition so I am on the fence.What say you?
