I currently have a 1956 Gmc pickup and right now from the previous owner he installed a glass pack on it. I want to tone the sound a little bit by changing the muffler. I have a 270 straight 6 engine right now. I want dual exhast but i only have a single header. Can I put dual exhaust with a single header and just "Y" split the exhaust? How will it sound? Will it work? ANy suggestions? Thanks in advance, Bizz
RE: Exhaust HELP and Suggestions PL [updated:LAST EDITED ON Jul-07-05 AT 06:18 PM (CST)]yes, you can dual out on a straight 6, but make sure that you do not go to big in diameter on the ppipes because you still need back pressure for the engine to run well, personally i hate glasspacks and cherry bombs. i sugjest that you get flowmasters, they will make a butiful noise. i also say that you should go no bigger than 2" on your pipes, anything bigger will cause yourhead to start suckng(very,very bad)...goodluck 1974 chevy shorty built 350 edelbroke intake and 750 carb high roller cam flowmaster dual 40series 12bolt posi rearend 3.88 gears
