    Hi all,

    Getting ready to redo my exhaust, muffler and tailpipe. I was looking for opinions on where to exit the tailpipe, i.e. in front of tire, behind the tire, or straight out the back?

    It was a stock set-up and went out behind the drivers side rear tire.

    It would be easier though to make it exit in front of the drivers side rear tire, any drawbacks to this?

    Thanks,

    John

    Something to think about is how much of that exhaust will be sucked back into the truck with the back window rolled down. On my 84 with duals running out the back at *around* a 45 degree angle, I get a hint of exhaust at highway speeds with the back window rolled down. A buddy riding with me said it was bad, I guess I'm used to it. Just a thought.

    Maybe just noise. And you might squish it in the future off the road. Strait out the back might fume you to death if you roll the window down back there in the summer. Behind the tire works well but is more costly than in from of the tire.

    It might just boil down to personal preference.

    straight out the rear looks best put some bell turn downs on the tip and you wont get fumes throught the back window. /forums/images/graemlins/thumb.gif /forums/images/graemlins/k5.gif

    Thanks for the fast replies fellas,

    Yeah the cost thing was why I was going to run it in front of the tire, plus I wouldn't have to wait for the tailpipe, have to order it and I wanted to do the work today.

    Thanks again,

    John

    What about running the pipe over the axle and dumping just aft of it? Would exhaust fumes be a problem with a setup run like that?

    Are you doing it yourself or taking it to a shop?

    I would be taking it to a local shop. They did my daily driver exhaust and I was very pleased. Great work at very reasonable prices!

    A friend works at a shop and is doing the work, well his boss is. Anyway he said that if I wanted to go behind the tire (like stock) it would be cheaper to just buy a tailpipe ($37), rather than spend the time to bend one to go up and around the axle. But they don't have the $37 tailpipe and it needs to be ordered. So he said they could easily put on a new muffler and exit it in front of the tire.

    Make sense? Sounded reasonable to me.

    Makes sense to me. Are you going to have to go to Twin or is the shop up there? Its been a few years since I've passed through there.

    The exhaust will discolor your wheel, when in front of it... if that matters. Ford did it on some F-150's for a year or two, had to switch it to behind the tire b/c of that problem.

    Actually the shop my bud works at is in Wendell, 15 min. west of Twin on the interstate. We just swapped rigs for the day, so he could work on mine. I am liking driving his early '80's burb with a mildly built 454 for the day. /forums/images/graemlins/smile.gif

    Is that where they have all of the big trucks for sale on the right hand side of the freeway and the gravel pit full of water that you used to be able to rent jet skies at?

    Good point,

    Something to consider anyway. Although I am not too concerned about looks.

    Thanks,

    JF
