Ferd/289 Posted February 28, 2004 Share Posted February 28, 2004 Not much room to install a conventional muffler under my '77 280. Now I am thinking about a Supertrap muffler at the tail end of the tail pipe, which would solve this problem. Also, when racing, I can take out the disks. Has anyone ever used this setup?

strotter Posted February 28, 2004 Share Posted February 28, 2004 This is exactly what I did. I had a noise problem with a pair of Borlas on a dual-exhaust smallblock setup. Got a set of the SuperTrapp "tips", did a bit of welding, voila! Now I can adjust my exhaust note from "obnoxious" to "civilized neighbor" in a couple of minutes. Back-pressure is inversely proportional to noise, pick your poison. Note: the SuperTrapp tips are about 4" in diameter; that's a large-diameter exhaust tip. They look big in the back of a Z; I'm not entirely happy with their appearance. Your mileage may vary. Quote Link to comment Share on other sites More sharing options...
