    so i been thinking about changing my exhaust a bit so i could get a better tone. right now im running a stock plymouth falthead 6 with reds headers. with a 25" thrush glasspack and a generic 12" glasspack. im using 1.5in pipe all the way to the back, and im not getting the rap i want. i used to have it straight piped and i love the way it rapped but was to loud for a daily driver, so im looking for something a little bit quieter than straight pipe. will the shortest steel pack from mellow tone quite it down a bit more than straight pipes, and i want them to rap a lot. any other suggestions? and i also had one straight pipe and with a thrush glasspack on the other bank and it was still to loud.

    They may quiet down a bit but the steel will most likely burn out to the point that the little Mopar will have a nice rap to it. One of the "older" neighbor kids had a Mopar ragtop that sat about that low and had one of the sweetest pipes I ever heard on it but I have no idea what they were as I was about 13 at the time.

    I ran straight pipes out the back, it wasn't loud, and had a nice lope...

    My 230 was perhaps 7 to 1 tops. It was quiet....

    Are the mufflers near the front or the back? (The farther forward, the more rap.)

    Was the one muffler on the passenger or driver side? Which side is the long muffler on?
    The bends in the pipe have a large effect on the volume.

    headers, 1.5 tube, short glasspacks forward as you can,pertronix helps but compression is king.

    Brock can make them with no packing if you like, to eliminate the time it takes to burn out the steel packing.
