As some of you know, I'm running a R460 through a Staton chain drive. Performance of the 460 is great but it's very loud and I've been using secondary silencers to quieten it down. I've built several, each one an improvement over the previous one, the goal to get the noise down to the level of my wifes TLE43. My first attempts were straight through glass packs, culminating in my current baffled expansion chamber design. This works the best but I would like to combine the glass pack with the expansion chamber into a Gen IV Muffler.
The new design would dispense with the silicone exhaust tubing coupler as these burn through after only a couple hundred miles. The inlet of the new design would be sized to be a tight slip fit over the outlet stub on the 460's factory muffler. The outer jacket on the new muffler would be made from 2 1/2" exhaust pipe with all parts being steel and wire welded. I'm currently unable to post pictures so I've been forced to use Photobucket. I've posted links to photos of my previous designs as well as a drawing for the new design, comments and critique would be appreciated.
