I can understand the time and ability factor. I am speaking to guys who work on thier bikes often because they enjoy the do it yourself aspect.After market as a preformance item is a waste to me at best they might gain you a couple hp and to me the little bit you might gain isn't worth the extra $400 to $700 and so far I haven't seen an aftermarket that is better than gutted stock in preformance. Now I have only had a chance to play with D&D and Sceptre since I can't afford to buy pipes those were on bikes of friends of mine set up same as mine except the pipes.

I learned all I need to know about life by killing smart people and eating their brains.
