Hi all, I have a 2005 ktm 640 SM (twin pipe) with stock pipes that have been debaffled. These sound good but are just too loud for the early morning commute. I'm after quieter exhaust options, tried to find replacement stock pipes but had no luck, and the cheapest aftermarket option I can find is staintune but they're still expensive at $1200!! If this is the only option then so be it, however I want to be CERTAIN that they will be quiet enough for me with the restrictors in. I like riding like an arsehole and the noisy pipes atttract so much attention it makes it difficult. I like the idea of the restrictors as eventually I will tune and rejet so I would have a good tune with open pipes for twistys in the country side but I could cork it back up for commuting. Getting desperate enough to fork out for the staintunes if I can be sre they're sneaky enough when restricted. Any advice greatly appreciated! Thanks!
