Thanks Texas, thats what I was unsure about..........whether I would be gaining a thing at all. Hence, my question. Hehe. Would a Pro Moto end cap on my existing stock pipe be a good option in your opinion? Would I gain anything from that? Thanks in advance. I'm not real sure it will fit. You can always compare your exhaust to your buddies yz pipe. I'd check the snorkle plate to see if it is going to block installation and the outer mounting holes to see if they line up the same. Will you gain anything? I honestly don't know. Personally I'm leaving my uncorked stock exhaust on for now and spending on suspension until I find an exhaust I can't live without.
