The best mod to the exhaust is done accordingly.First thing is to remove the muffler and with a die grinder remove the excess weld restricting the flow in header pipe. Note some pipes are better than others but the vast majority needed to be cleaned up. Next step is at the rear of muffler. Using a hack saw cut off the 1/2" id tail as close to muffler as possible. Drive a piece of 1/2" wood dowel rod into the tail, this will allow the use of a 1" hole saw by acting as a pilot. Drill out the rear of muffler using the 1" hole saw. Next get you a piece 2"-3" long of 1 1/4" od electrical conduit. If you know any electricians they would have some scraps. Drive the conduit into the rear of muffler than weld in place. If no welder take to a muffler shop and they will weld it. You will have released the excessive back pressure and give you a low throaty sound. Noise level will increase slightly. Note, removing the inner muffler baffles will only hurt your performance and give you a very loud buggy. Oh, and welcome to the addiction.
