Exhaust set up idea
Back in the Miramar days, a kid had a '55 Chev, 327 I think, got a noise ticket. Went out and bought a new set of headers and Cyclone "Purple Hornies." He said the state cop wouldn't even come out of the office, just waved him away. Next day he was welding in about 4 old mufflers and flex pipe he dug out of the trash big at the auto shop. And of course the day after that the purples went back on.
I don't like 'em. Obnoxiously loud, in or out of the car, and subject to uh, "resonance" at several RPM ranges
