To be more specific: I work at a Suzuki dealership. I have customer who recently bought a new SM, who installed (himself) an MRD exhaust. Last week he came in with the rear shock shaft seal leaking. Our mechanic suggested that it could be from the MRD exhaust being so close to the shock resevoir that it overheated the shock/shock oil, causing expansion and resulting in the seal failing. Has there been any reports of this type of problem with the MRD or other exhausts? I personally don't buy it, and we are replacing the shock for him under warranty. But if that is the cause, I'd like to know about it and be prepared. Thanks in advance.
