I recently was blessed by the mass state inspection telling me my exhaust was rusty and I said YIPPEE, what an excuse to buy better exhaust. I ran with mac 1 5/8 equal lengths, offroad hpipe with hi-flo catalytic converters and american thunder by flowmaster. My ride sounds MEAN but in a controlled, muffled roar sort of way. I heartily recommend at least the american thunder!
Happy trails
