I knew that I needed new exhaust anyway and decided to replace the stock muffler. When I took it apart, virtually every connection to the exhaust ports had some kind of leak. After I installed the new muffler, the rumbling sound on deceleration you described stopped. If you can see the connections to the exhaust ports, they will have a black sooty deposit all around the area if it is leaking. Good luck. Steve B.
