    Got the 408 comin with pacesetters and ORY pipe. Was thinking about a single 4" from the Y through a 4" muffler and dump over the rear axle. Waddaya think?

    depending on the muffler, it may not be too loud.
    As far as flow, it should be good.

    Sounds like a great idea. Just be sure it turns down and out or you&#39;ll feel it rumble through the cab. That is going to be a stump puller of a reliable engine&#33; 11:1 compression? Badass&#33;

    I do NOT want loud. When I say "dump over the axle" I mean out the back at the bumper, but unseen. There&#39;s nothing I hate more than exposed exhaust. Make it look factory or hide it alltogether. Would duals be quieter?

    Not 11.1:1 compression. Decided to keep my 72cc heads and do 10.5:1. Will be adding 150 shot after we&#39;re good and broken in.

    You may have to experiment a little with mufflers to fing what you want.

    I wont need no "stinking" muffler. I&#39;ll have one of those butt turbos to keep it quiet.

    instead of dumping it, have two tips exiting the side before the tire. that always looks good and shouldn&#39;t drone as much.

    i&#39;m thinking about going that route with my corsa after i get my headers.

    agreed&#33; two before the rear wheels&#33; always a winner&#33;
