My Yoshi slip on I bought wont seal right. Well basically the heat insert piece that came with the pipe was messed up a little bit and also when I put it into the pipe and tried to connect it to header pipe it would just push that piece back into the muffler. So what I did was use the stock heat insert piece and put the muffler on and it fit fine but when I clamp it down I have it as tight as it would go but it leaks out of there. Any Ideas? Maybe tape the heat insert alot to fill room? Do you maybe think I have the pipe pushed on to far or something? I really could use some help guys.. Thanks alot O ya It is a 03 Raptor

 

I don't have the Slip-On but they should install the same. You may want to take a look at some of my photos..........maybe one will show you something that will help you.
