ok everyone, just bought a yoshi 4-2-1 system. i cannot figure this out. i installed all the parts, looks great, fired it up, and wow! what a noise coming from the headers. it appears that the header is not seated to the engine, like it should. all the springs are on, is there a step im missing? is the only thing holding the headers on is the springs? that cant seem right, i can look where the header meets up with the engine, and i see a gap. any help would be just great. thanks- adam
