Hey guys just pucked up a 09 yfz r going through it all making sure it's ok. One question I have is it came with a big gun Eco slip on where the pipe meets the header it does not fit snug or tight. It's loose enough that I'm getting exhaust blow by on my cylinder head. I have taken it off and rechecked the clamp but all is tight. Is there something I'm missing or do I just need a better system? Any help would be appreciated.
