Here is a picture of the stock exhaust, I need help in modifying it. What should I do to make it a little louder without affecting the performance negatively. The exhuast comes into the center chamber, which is sealed off except for 2 crossover pipes, one of them you can see, then the exhaust goes into the outer chambers where it exits out the exhaust pipes. There is packing on the sides of the canister, held in by a mesh plate. Anybody done theirs yet?[/b]
