I can run open megaphones at Willow Springs and (I think) Buttonwillow. But if I venture out to tracks with noise-restrictions, obviously I will need to run a muffler setup.
Car will have Bursch headers, for now. What are my best options? I have seen some nice stainless "can" style mufflers from Coast Fabrication, which look very similar (maybe identical) to the ones sold by Jim Patrick. In terms of stock-ish style, I have heard good things about the Monty stainless 2-in/2-out sausage. There were some at the Dunkels meet this year and they sure looked purty, but spendy (>$600 IIRC). Supertrapps are also a pretty common setup. What are my best options that won't get me black-flagged at the track or arrested if I take the car out on the street, but hopefully also won't kill too much power or wallet-padding either? If I ever take the car up to Laguna, I'm assuming I'll have to meet 92dBA, which is a beotch even in a stock early 911/914-6. The carbs alone make a ton of racket and there's no sound-deadening in the car anymore; plus a GT-style engine lid. (I have a spare stock lid if that helps). |

Another option is to go to a rally style muffler. Mine is similar with two in and three out. I cap the middle two for silent running and pull the caps off when I want more oomph. I took the design for BA's 911 hand book. Originally the factory made the muffler to fit over the megaphones and had the outlets (same size as megaphones) directly behind the inlets. That way they had a choice of free flow or capped and one side muffled outlet. My muffler is a little more 'off the shelf"
