FMF Factory 4.1

I have a 2007 YZ450F with FMF Factory 4.1 exhaust I crashed pretty hard and bent a dent in the end cap and I have another muffler with a good end cap and was wondering if I can take it off and put it on the other muffler. If so how do you get it off?

Yes you can, you have to drill out the rivets and rivet the endcap back on. I'm assuming you have another factory 4.1 that you are stealing the end cap from. You won't get an end cap from a different type of pipe to fit.

Yes I have an old 4.1 with a good end cap. Thanks for your reply.
