    Where my exhaust currently is routed, the fumes seem to come in the rear window. Eventually I plan to go to a soft top. Where should the exit of the exhaust be located?

    i have ridden in 5 different blazers all with different exhaust. and the way mine is now(dumps before the rear axle) seems to let the let exhaust in the rear window
    however, i am pretty sure you will always get some exhaust in through the rear window
    one thing you might look into is the spoiler that came on some of the trucks, this might help a little bit.

    All i have been in sucks it through the rear window. Its just the suction of the air rolling back into the cab. one thought is maybe an exhaust that exits to the sides infront of the rear tires. But it may still do the same.

    At an angle behind the tires works good on my truck...and mine is a diesel so there'd be no question if it was sucking exhaust fumes into the truck.

    I remember seeing in 4wheeler mag several years ago exhaust dumping into the rear wheel well. Could the turbulance pull the fumes away?

    It would while you're driving. But most in-cab exhaust leaks/problems are more noticable sitting at stop lights and what not. When I get mine done, I'm going to have them at an angle out the back.

    Mine exit down in front of the rear tires and I don't get exhaust thru the back window but through my driver and passenger front windows. Not fun.

    Mine's currently cut off right behind the muffler, directly underneath my rear seat. Fumigates everyone in the back...:p: It's pretty bad right now. Oh well. I'm going to run it out so it exits to the sides in front of the tires.

    Depending on how they're angled out the back, your rear leaf springs may hit the pipes. I had mine done like that but when I drive over stuff or hit a pot hole in the road I can hear them hit. Just something to keep in mind.

    I know straight out the back totally sucks. I even had them turned down. the exhaust is my next expense along with a drivers window motor. I am going to aim it out the sides all the way at the back.

    Mine is on the drivers side behind the rear tire. I have never had a problem with the exhaust coming in through my rear window.

    I just ran the factory dual stuff, and it's about as good as it can get I think, compared to others experiences.

    The factory spoiler made a big difference, but didn't eliminate the problem. You are talking about going soft top, so that's out.

    GM wasn't cheap when they did the exhaust exit, you'll notice (our) factory stuff exits out the side, but the tips are cut at a 45* angle to allow the exhaust to exit out the side of the vehicle, yet down towards the ground.

    Cruising with the door windows down and the tailgate window down the exhaust is imperceptible, but from a stop when you accelerate is when it's noticeable.

    Mine used to exit out the side about a foot in front of the rear tires. I had it angled at a 45 toward the ground. It was better than straight out the back or exiting out the sides behind the rear tire, both of which I have had.

    Now with the sliders and lift I have them cut off about a foot after the mufflers and they angle toward the sides and I cut at an angle toward the ground. Still stinks but oh well. Going down the road I don't get much but stop lights and slow wheeling make you stinky. Probably has something to do with the junky motor though.

    My biggest problem is my wife. She is very sensitive to those kinds of smells. I am afraid if I don't find a solution, she will never want to ride in it.

    Mine has been changed several times over the years. Due to the influence of friends and family I dont smell it often. But out the side behind the rear tire has seemed to be best. The only way I been able to completely eliminate it is to take the top off. I did also replace all the weather stripping and silicone any other holes which made a big difference with the top on. If there are any ehxast leaks at the eng or collectors the smell is much worse.
