Not an exhaust leak but I've been hunting for a rattle at certain rpm's for 5000 miles, lol. Well, the metal support bracket at the crossover pipe is an afterthought apparently. Metal on metal and loose enough when tightened to cause a rattle when the pipe vibrates against it. I shimmed it with a washer to tighten it on the pipe and noise is gone. Will figure out how to rubber coat it now that I've found the source.
Does everyone have this problem? What's different about this clamp on my RK?
I have the same rattle on my '17 RK. It drove me crazy until I found the cause. As soon as the pipes warm up, the rattle goes away. If it's still rattling at 5K, I'll have the dealer address it.
