Good point... I think my plan has been foiled! Mine look just like yours and sit up against the swim platform also. Unless the hinge is "smaller" and doesn't extend upwards as much and if the flaps don't "over extend" they won't work on a 32. Maybe HyFive can comment on these issues?

I have plenty of clearance above my exhaust tips. As for the internal flapper, you have a few options.. You can get the ones you originally posted about... they are reasonably priced and appear to be easily installed, you could have new internal flappers welded into your existing tips or you could replace your exhaust tips and get those with a better internal flapper (I bought those from Teague on my 38). As for the external flapper, looks like you have minimal clearance but should be able to use a standard black rubber flapper. The SS ones probably will not work if your tips are that close to the bottom of the swim platform.

Yes my rubber ones rub on the swim platform. Are your "new" ones as tall as the old rubber ones and do they have anything that "limits" the upward travel of the stainless flap?

Haven't compared them side by side, so not sure but the big difference is that the rubber ones will flex if the clearance is tight, the stainless ones, will not. There is a small steel "nub" on the back side of the hinge that does limit the travel. I don't think it will go past 3:00. I haven't installed them yet so really haven't looked at them a lot. Here's what they look like..

You can get this flap and the muffler comes for free!

Still comes out cheaper than the CP part.
Wish they made em in a 5" for my current set up.
I ran the 4" and they are a very nice quality piece.

Dan, how long did they last (hours)? And what kind of power was if front of them?

Diamond Dave

For sure not fitting after seeing the side view pic you sent... BOO! Please post up some pics in the other thread when you get them installed I would still like to see how they look!

Those look sweet I really like the look of them! How much did they quiet your engines? If they start imposing some noise restrictions here I will for sure go that route but I like it loud for the time being with my measly 502's... I like sounding faster than I am lol.

It`s only muffled at idle and even then it only takes out the bark. They set the spring pressure according to your power level so at speed they are open .

neat idea, but I wouldn't substitute those for flappers because of the slots on the bottom you are going to loose the check valve effect, which can make the engine more prone to reversion. Remember Budman's reversion thread?

Diamond Dave

They claim on their site that they "Eliminate Exhaust Reversion" but what you are saying makes sense with the holes I see in them. I thought maybe there was another flapper up inside them but I don't think that is the case after looking at them more.
