what would be the best way to have my tailpipe come out before my rear wheel. i have a 1993 5.2 4X4. i looks like i would have some weird angles if i did do it because the muffler is the same height as the frame. any ideas

 

I think (from pics) that the user Hahns5.2 does that. Check it out.

 

Yes, I had (and still do) have a before tire exit.


And now with the turbo the exhaust goes over the frame.

 

thats what i thought, if im thinkin right, but i still might be wrong, my muffler is sittin higher then that, ill check to see

 

im thinking of doing this too cause the shop did a ghetto job when they connected my existing tailpipes to the new muffler so im thinkin a cheap diy fix would be good like this.

 

No offence, but the preturbo Hans5.2 exhaust is incorrectly angled (or rather inappropriately angled). There is pressure across the surface area of the outlet as speed increases, whereas with the exhaust pointed rearward would produce a vacuum effect (venturi principle). I personally hate side pointed pipes, because of traffic noise and typically point them downward past the axle to reduce noise and simplify aesthetics. Your truck though. I like the post turbo exhaust, but it is atypical and affects the rear tire in terms of longevity and grip with aggressive driving.

 

The design of the Aero Turbine muffler will produce more vacuum effect than exhaust tip angle. And air rushing across the exit perpendicularly will also create the venturi affect. I like my exhaust pointing straight out the side, both for aesthetic reasons and sound quality. I hate dumped exhaust, I think it sounds like garbage in the cab, I don't care what other people in traffic think my truck sounds like, it's not very obnoxious. And I can assure you the tire is fine. The only reason it no longer points out the side is space limitations, but I plan to get another 3" U bend and should be able to make it exit straight out again with a little ingenuity.

I also have a side exit on my Bronco II

 

For clarification reasons:

The muffler deals with vacuum pulsations from the exhaust ports, as does the catalytic converter (due to expansion chamber reflection). Whereas the exhaust exit "ideally" deals with venting of the gases to the atmosphere. I must fundamentally disagree with the 90 degree vector of streaming air causing a vacuum at the (or any) exit. De laval is typically used for the "flaring" of the exhaust exit (among others), but given the ideal shape of an object to reduce restriction (at sea level), the principles are sound. By pointing the exhaust away from the streamline, the vacuum is caused by a low pressure (ie there is an object in front of the exit during acceleration and speed) area or trailing area. When the exhaust is at a 90 degree vector, the slipping does not provide for low pressure.

While the above is a grossly simplified standpoint, if you can give any primary source of information that differs, I would be greatful to read it, as I have never heard that before.

 

Follow up to OP:

My recommendation is approximately 7-21 degree's down at 45 degree lateral angle. As vertical angle decreases, lateral angle should increase and vice versa.

 

You act as this makes any real world difference, it's like suggesting ram air actually does anything on a street vehicle. Putting way too much thought and time into something that really doesn't matter.
