I got a NIP trinity exhaust with my revo when I bought it, and now that my traxxas header/coupler has cracked I've finally decided to try it out. Problem is that I lost the seal that goes from the header to the engine... Bought some of these from THS http://www3.towerhobbies.com/cgi-bin...?&I=LXLTV7&P=7 and although they fit on botht he header and the engine seperately, they won't slide on while inside the header. It seems as if the gasket is too thick.. Anyone know what I can do or what type of seals would work with the trinity header??
