    What are you guys thoughts on having the exhaust exit infront of the rear tires. Would there be too much exhaust in the cab, noise isn't really a factor, being that right now i don't have carpet either. thanks for the thoughts

    if your tub is pretty solid, you wouldn't have to worry about fumes much. Although witht he pipe in that location, it make them prime targets for rock, logs and whatnot that like to bash things...

    I have always liked when they come straight out the back and run the pipe in between the very rear spring hangers and the gastank... Thats the way mine used to be and wish they still were...

    If I had it to do again...it would be side out...can't roll my window down unless i want to suck in fumes.

    Mine doesn't exactly exit. The pipes just end right after the rear axle. Not much chance off damage there. And no fumes either.

    That's because I'm the devil.

    I agree with lehtola. I have mine coming out at angles on the rear corners and when I had the rear window rolled down (when I used to have a rear window) I would get a heaping helping of exhaust fumes. I also thought about puting them in front of the rear tires, but I think the noise would drive me crazy. Those flowmasters are not the quietest mufflers.

    Didn't look where you are from but in california it is only legal to have them come out behind the tires... Can't even have them straight out the back cause that is illegal also, since the rear window rolls down. Mine come out on each side behind the tires.

    i agree with max crack. Mine exited between spring hangar and spring after the shackle flip. Figured they'd cause more damage if ripped off by rocks so I sawzalled them where they dump right after the hump over the rear axle. That sould eliminate fumes, trail damage, and black spots all over whatever is facing the pipes upon startup!!! [​IMG]

    I have mine exiting out the sides behind the rear tires, but I still get exhaust fumes coming in thru the rear window.

    I've got a mind like a . . . a . . . what's that thing called?

    I have a single 3 inch pipe exiting at the stock location behind the driver's side tire, and still get fumes when driving with the rear window down.

    I have true duals exiting at 90 degree's behind the tires and sometimes I get fumes through the window, but it's only when I sit idling for a long time(ie traffic) if I'm moving along I get no fumes

    Even out the sides (behind the wheels) I suck in fumes through the rear window. Even in my Burb, which has the air foil across the roof to prevent the fumes from comin in....they still come in.

    I've got mine coming out right behind the rears at 90 degrees, and still get enough exhaust in the cab to kill a horse when the window is down.

    If it weren't for bad luck, I'd have no luck at all[​IMG]

    The only place I've found for decent rock protection is in the factory location, at a 90* angle behind the rear tires. I have a single 3" pipe on the passenger side, full length headers that Y behind the t-case, and a passenger side flow master big block muffler. Nice and quiet.

    mine exit behind the rear tires at 45's, but I'm assuming Pugs is getting fumes when his rear window is down. You should NEVER run with your rear window down because it creates a vacumn and sucks everything from the rear into the vehicle.

    I had mine bent so that it drops out just in front of the rear axle and points down. I was having a problem with the axle hitting the exhaust at full articulation.

    JEEP it's what's for dinner!

    What about soft tops. Does every one with a soft top have to run with the side windows up and the top sealed?
