I just got a complete pro circuit t4 exhaust system for my 400ex, and it didnt come with the high temp o ring where the silencer fits over the header. I have tried to look around on the internet but I still cant find one. The exhaust leak is pretty bad so if someone can help me that would be great. thanks

 

i couldnt find one for my e-series so i just used exhaust tape but it still leaks a little bit,if you find one let me know.

 

Ya, its lame that none of the magazines i have sell the o ring but sell the silencer. for now i found out that cutting a mountain dew can or any other can in a strip that is wide enough to fill the gap works alright but im sure there is still a leak, but its better than nothing and you cant see it when its in. Putting it in is kind of a pain in the a$$ but it worked for me. hopefully that'll help anyone that has the same problem.

 

i was actually starting to think with mine the slip on isnt made to fit the header or something cause the end of the muffler were it goes to the header is WAY to big for the header,i bought them seperate cause at the time magicracing.com was sold out of the full systems for my ex so we just threw on some exhaust tape and it still leaks a little but not as bad.

 

They do fit very loosley but its because of the o ring that is supposed to be there. im going to call pro circuit tomorrow and order the o ring.
