Hi folks, im brand new to this forum but i thought i would give it a shot. anyways i bought a new slip on pipe for my trx. Im looking for tip and tricks for installing it on my bike. Also what i need to do once it is installed. im new to the quadding world but im learning quick. I pulled the old one off last night and where it joins, it has like a tin foil substance. not sure if i need to scrap it off and put new stuff on or what. Any tips would be greatly appreciated thanks!
