My current exhaust consists of a 3" down pipe with 4" straight pipe to 5" curved stacks. I love the sound driving around town but on the highway or towing my camper it's way too loud. I'm looking for a straight thru style muffler that will fit over the 4" pipe at both ends. If any vendors can help me out pleas pm me and let me know. Also if you could give me the over all length of the muffler, tip to tip, I'd appreciate it.
