Side Pipe Mufflers

[Bill E]

Not a new Idea a good one but not new. We did our first set almost 20 years ago. I could not get any one to buy them in the kit market. Cost was the mane factor. I have a new side pipe with a removable muffler tube and have been installing them. At about the rate of eight sets a year. WE have all so figured a way to keep the external timp down to 178 degrees with an internal timp of 575. Our next trick is to pass the sound check at Laguna with 1300 HP If you can figure that one out keeping the side pipes. I would like to here about it. so far we have come up with capping the out lets and running 3" tubing to a large can in the trunk and putting six oval holes in the deck lid .

Thanks Bill, i was quite sure someone had come up with idea before me. I have no interest in finically gain just want to contribute to our hobby.

My design starting from the collector and working toward the muffler is as follows.

Front muffler cone is welded to the collector, a machined fit ring will fit over the collector and under the front edge of cone to maintain uniform roundness and for self alignment. The aluminum ring will have a machined fit to the collector and will be attached via stainless pan head screws from inside the collector. The machined ring will be tapped vertically and horizontally. The perfrated core will have a slip fit over the collector and a welded flange ring on the front. The perforated core flange will attach to the larger ring via pan head screws. The perforated core will be wrapped in ceramic mat and will allow the rear of the core to float. The muffler housing will slide over the Matting and over the machined aluminum ring (the ring will create a very snug fit). muffler housing will attach via pan head screws to the machined ring(there s a self alignment dowel on the bottom of housing (out of sight) so that when muffler housing is tapped into place perfect alignment is achieved).

To replace core do the following:
1. Remove muffler housing screws and pull housing off
2. Remove core screws and remove core
3. Slip core new over collector and screw on new core (core is already wrapped in matt).
4. Align housing and tap into place, attach screws.


I have left out some other details, however; the general design concept is conveyed. The design is for natural aspirated engines.

If i made a few mistakes in grammer or syntext do not flame me. I am in bed with the Flu.
