New headpipes, gasket question
Got my dresser duals in yesterday and was wondering if I should use the supplied (V&H) exhaust gaskets? Before I recieved the duals I took a trip to the dealer and picked up some new factory gaskets (non screaming eagle) and muffler clamps. I didn't know the pipes came with gaskets. The difference is the factory ones have a bevel on one side for the headpipe to slip into. The V&H ones do not.

The best and easiest to use gaskets are the H-D Screamin Eagle exhaust gaskets. They seem to seal better than stock gaskets. Also, I would only use H-D pipe/muffler clamps rather than the V&H clamps. When I put my mufflers on the V&H clamps were rather cheap and definitely one shot affairs. H-D ones seal much better.

Oh and ditch the flimsy V&H clamp (I think they only give you one) and use HD clamps (3 of them).

As for the clamps, that must have been a long time ago because I just looked at the V&H ones compared to the HD ones and they look identical with the exception of the nut to tighten the clamp. One is a little longer than the other. They even have the exact same markings on them.
Really, high temp RTV? I would think that is not needed since the mufflers slip over the headpipes. Now if they slipped into the headpipes, I can see maybe using RTV.

Would think either one would be fine. I use the cometic stainless steel exhaust gaskets myself, and really like them. It's part #C9540, 10 for $72. I replace em everytime the exhaust is removed, but I'm just picky that way.

I installed my Dresser Duals 1 month ago without RTV and 2 weeks later, my right CFR muffler started to turn goldish at the junction, right past the heatshield. During the previous 2 weeks, I've re-tightened the muffler clamp several times. So after getting rid of the discoloration with Blue Job, I pulled the 2 mufflers (PITA by the way) and smeared the inside of the flange with RTV red. It was very easy to put them back on and since then, no more discoloration of the muffler.
I guess the clamp didn't completely seal the muffler over the headpipe and created some discoloration. That's the only explanation I can think of.

Well, I dunno. Here is what happened to me.

Don't think I have to worry about discoloration since thery're black. I'll keep this in mind when I get to that point though.
