| Steve,
Yes, that would be me, "Mr. Muffler" himself. The Moroso style muffler didn't muffle very well and it kept melting the bolt holding the baffle in place. I finally went with a SS bolt which didn't melt. In an effort to find something that wasn't as noisy, I discarded it for the DNA muffler which wasn't much quieter, but it survived the harsh rotary environment better than anything else I had tried up to that point. I'm now running an inconel 625 tangential muffler, which is the best as for noise attenuation I've used to date. The only problem is that I suspect I'm losing hp due to excess back pressure. But at leaast I can hear to talk on the radio. Its my opinion at this stage of the game that the best muffler is a turbo. At least you achieve a fairly quiet exhaust note, and get some extra hp too.
