So I have an APEXi PS Revolution. It's a sweet exhaust, but the only problem is the silencer valve inside the muffler. I'm wondering if anyone else has this exhaust and this problem...

The way the valve works in the muffler is pretty much a spring-loaded plug. In the muffler there is a long rod with threading on the end of it that a plug goes around that is plugging the flow of the exhaust. The plug is held in the hole by a spring, and the spring is held in place by a weird round thing at the end that kinda looks like a turbine that screws onto the rod. When idle the plug is barely pushed back by the exhaust pressure, but during open throttle it pushes the plug back further to make it louder.

The problem is, the thing that holds the whole assembly in place (that weird turbine lookin thing) keeps coming unscrewed and has actually fallen out one time on the street. How the hell can I keep it from coming unscrewed?

Any ideas?

Can you take that apart and put it back together with high temp. loc-tite? Otherwise, ditch that thing. Seems more trouble than it's worth.

well I was wondering about that...do they make high temp loc-tite, and would that work...would that make it sit permanently in place? I can't really ditch the whole exhaust without getting a brand new one...the silencer thing is built into it.

I did a quick search and only saw 450 degree. You can try copper sealant which is higher temp. or even better, can you double nut that?

Well posting on here made me remember that it was threaded and i went down to the hardware store picked up some washers and M10 nuts and that seems to have fixed it...don't know why they sold the exhaust like this, I'm sure they made it to be adjustable, but I have to tweak it just right otherwise the flange provides either too much or not enough back pressure.

But yea, a nut and a washer solved my problem, thanks for the help.
