I don't want to waste money getting head work done, I don' t want to port, polish, map, blueprint and so on. I don't want to increase the compression ratio to 20:1 where I have to use 116 octane sunoco race gas. I don't want to put spinner hub caps on to 26" rims. I don't need someone to tell me how slow my motorcycle is compared to a stock goldwing all I want is for the exhaust on my 07 to come close to that on my 05.

It sounds like in your head you have it all figured out, so why the waste of bandwidth. Go get yourself a set of 05 head pipes and mufflers and weld O2 sensor bungs on and see what you get once installed, it won't be what you have running around in your head. I'm also betting that if you keep setting your bikes on the shake and bake setting by idling for an entire tank your going to have an excuse to take your engine apart and repair the carnage left behind by this practice. I do know for a fact that my bike with ported heads and increased compression ratio and bigger cams is cooler than what it was when stock, my oil temperature tells me so.
