Well, I managed to cut off the old mufflers and get a couple Thrush glass packs under there. The pipe from the muffler back was actually in pretty rough shape, so I just cut out a couple good parts and now the exhaust dumps out right in front of the rear axle. Is this going to be a problem? I did angle it down, so it's not blowing straight back to the axle or brake lines or anything.

By the way, it sounds pretty cool now. Can't wait for the packs to break in.  ;D

Thanks to everyone who replied!

Not sure about were you live. In N.H. for inspection and hard ball cops they have to exit behind the tires if the truck has a slider. If its solid back glass they have to go 18' past the cab and turn down and out at a 45 degree minimum.

I assume you're talking about the rear window? It's a solid window. I can probably twist the pipe I have in the back of the packs and add a tip that points away from the truck, in front of the rear tires.
