Blue Flame Evo 3 legal twin port Report

Hang on, I'll look into my crystal ball.....

Seriously, these is always vibration within an exhaust, as it is solidly mounted to the engine. The original rivet may not have been put in correctly, or may have split inside the exhaust, which you cannot see.

A stainless rivet should solve your problem though. Make sure you get the correct size (diameter). Probably 4 or 5 mm rather than the 3.3mm which is the most common size that you buy. You should look for one which is at least 8-10 mm long to ensure that you are pulling the two metal surfaces together as well.
