CJ exhaust route-smell

Something needs to be done on my CJ for exhaust routing. I am tired of smelling like exhaust. I currently have dual pipes exiting at the rear of the jeep on either side of the gas tank. I believe this is a majority of the problem. My plan is to exit closer to the corners and I have a couple of options (pictures below) I am seeking opinions on. . .

Option 1. Custom 90 Long or Short- $ 160 -
Option 2. Custom 45 -Version 1 or Version 2 $160
Option 3. DIY $25

All the photos are here: http://1drv.ms/1cUhxUB

The number one goal is to get rid of the smell. Do you think any one of these configuration will have an advantage over another in terms of smell reduction? Any other suggestions (pictures help a ton). Number two goal is the way it looks. If you think all will be an equal improvement; which way do you think looks best?

Anyone who has experience with this is greatly appreciated. . .

I'll post my results once I get something done.

My CJ (green jeep) has the same problem with the soft top rear window removed. With the rear window in or the hard top, it doesn't seem to be a problem. The YJ I had didn't have that problem. Below are pictures of the exhausts of both. Angled out at the rear seems to be the way to go.

What Will said. No matter where the exhaust comes out, some combination of driving speed, wind direction and top configuration will bring it back into the Jeep. Don't spend money trying to fight mother nature; you'll lose. Just make sure the exhaust system is tight and close off any holes in the tub.

EVERYTHING's easy for the guy who doesn't have to do it.
