LOL! Too true!

I just am really paranoid about exhaust and find folks aren't aware of
how sneaky it is.

I posted a warning a couple years back about getting gassed out in a TJ
if you drive with just the soft top windows out and leave the doors on.
A friend kept falling asleep at the wheel and we went on a camping trip
in his Jeep. His girlfriend warned me about him falling asleep. Well
sure enough we were less than an hour into the drive and he is nodding
off. I took over driving and started to too, then realized we were
getting gassed by the forehead headache and difficulty keeping my eyes
open. I got the door windows open and cranked the fan to full and was
ok after I woke up buddy.

Well.... He still didn't freaking believe me!!!!!! He continued to
drive like that until he rolled his TJ on a sunny day on a straight
piece of road.... He still 'doesn't know what happened'....

Sometimes it's amazing how big an effect a little change in your exhaust
exit can have. When I finished rebuilding my CJ the exhaust dumped
straight out the back, just to the inside of the drivers side tire. The
fumes just about killed me from time to time. When I was driving, even
on the highway, I'd get clean air, exhaust, clean air, exhaust. I could
feel it swirling around me. I changed it so it made a little dog leg at
the rear to dump just behind the rear tire and pointing slightly down
and I haven't had a problem since. Basically I put it back to its'
factory location (damn, sometimes engineers do get it right!).

Highway, trail, top, doors, windows or any combination thereof and I
don't have exhaust fumes any more. I was pretty amazed at what a
difference such a small change made. I'd have to say the exhaust tip
didn't move more than 8" +/- but it was all the world.
