Yes, that would be me. They hold up great and look great. I removed them because I was continuing to have reversion issues with my rear engines. This was complete speculation but there was a possibility that the flappers were trapping some water due to their weight by not opening sufficiently under idle exhaust pressure. Not saying the flappers are the cause but I am trying to eliminate any and all contributing factors.

I have the rubber ones and they work great but don't look great.
My question is do the rubber o rings on the stainless ones really keep them from making a clinking noise as they bounce open and closed?
I have a few trucks at work with the stainless flappers on the stacks and all you hear when they are idling is clank, clank,clank.

[ATTACH=CONFIG]552877[/ATTACH][ATTACH=CONFIG]552878[/ATTACH] The Stainles flappers are nice quality and do not make any clanking noise. The gasket works to eliminate that. The design is an easy one bolt clamp on, BUT if you tighten the bolt too much the flappers will bind. A couple of the flappers were binding right out of the box, so I took then apart and clearanced just slightly at the moving joint. Much better looking than the rubber external flappers but also much more expensive.
