Hey guys, been looking at getting an FMF 4.1 (slip on) exhaust with the stainless mid pipe and titanium canister. I was wondering how well these hold up. Are they durable? Looking to put it on an 08 RMZ250. I really am not looking for a pipe that requires lots of maintenance or is junk in 20 hours. In my opinion, it should go at least 100 hours with only repacking required. Any input from others using this slip on would be appreciated.
