Does the Ames aluminized have deeper tone than stock? How was the install? I like the sound of the Race Pro system by Pypes, but I hear the install isn't as easy as the ad says, and I'm trying to avoid the muffler shop. Gardener is supposed to be top notch, but I haven't checked into the price of their system with turbo mufflers, it may be more than I want to spend. I'm in the middle of installing "concours correct" exhaust on my Mach I, it's going pretty well, except having trouble getting the tips centered in the valance. I'll probably end up at the muffler shop with it.
