As far as the muffler mod thing…How much you will gain, or more to the point how much you will notice, really depends on the engine itself… some are more responsive to a muffler modification than others. Typically a muffler mod begins with removing the muffler, measuring the exhaust port to determine total area, then modifying the muffler outlet(s) in some manor to 70-80% of that, and finally making carburetor adjustments… opening the muffler outlet(s) further than the “Magic” percentage will actually hurt performance. Under EPA regs, they will never be what they could be… and likely the EPA will soon hit manufacturers with new, more restrictive regulations that will degrade performance even more.
