whenever i drive my runner around with my rear window down, the exaust ends up in the truck. originally i had dual exaust on my small block conversion but when I went automatic (turbo350) i also went single exaust in hopes to eliminate this problem, but no such luck. any advice, or does everyone have this problem.

 

Fairly common problem. I found on my '85 that I had a few inches that I could lower the rear window and also play with having the sun roof open before getting exhaust in the back. Adding a wind deflector in back can help as well:

 

thanks for the info. i dont have a sun roof though.
