After 6 hours of cursing and turning wrenches, it's finally on!
I bought mhornfeck's Genius and on an impulse, decided to install it myself. I acquired the necessary tools and went to work.
Strangely, the catalytic converter heat shield took up 3-4 hours of time. I just couldn't get the screws to fit back in and it was driving me nuts.
Otherwise, I'm finding it pleasantly loud.
At low RPM, it kinda sounds like a Cherry Bomb Glasspack...But at high RPM, it sounds like a vicious racer!
