Here is my Jic-Magic exhaust that doesn't drone. What did happen is a couple exhaust hangers broke off, but it has been on for about 4 years. Just had it welded and it's ready to go back on. Not sure why it doesn't drone but I think it's either the pipe length or the muffler construction. The temporary exhaust is the lesser expensive ebay ones and it has that 2800 to 3000 drone. It's not awful but it's there. The Jic-Magic sounds so much better than the temp ebay muffler, and can't wait to get it back on.
