Stupid question, how do you check the exhaust for a leak?

Block the exhaust with your gloved hand over the outlet.
If the engine dies, it's ok. IF it keeps running you have a leak....

Still, running with the top off with the exhaust running straight out the back will have the fumes sucked right back behind the windshield.

Yes, where the exhaust exits out the back is important but you need to tune. I drive open air/bikini top and no doors but even after I had purchased mine, with the exhaust exiting behind the left rear wheel, I still smelled like exhaust because it needed tuning. After adjusting the carb, spark, timing and fuel pressure regulation, I no longer smell like exhaust, nor smell it. My kiddos would definitely let me know if I did. I know I have a leak under the seat but just haven't had time to fix it. Even with that I don't detect it.

First learn about your engine and it's systems by whichever method and then get it tuned correctly. It will help the performance.

So can I add a 90 degree tip to my existing exhaust, thanks.

Another question to your theory, how come this doesn't happen in my 2005 f150, my exhaust sticks out the back and my kids ride in the bed of the truck all the time and never smell like exhaust. Thanks

I got my pipe turned behind my driver side back tire and I still smell of exhaust. Went to my local jeep place and they said I should have cut it back so the pipe is under my jeep to where I can't see it and point it down. Any thoughts. Thanks.

Well, firstly, I'm sorry that didn't fix it.

Second, where the guy at the dealership said to put it is NOT where Jeep, the folks who built it put it. They put it in the corner where many of us suggested, and how many of us eliminated the fumes. The Service writer is either an overlooked genius, or as I suspect, mistaken. Aerodynamics; how do they work?

Here's hoping it's a chap easy fix.

I'd rather be lost on the trails than found at home!

Check your shifter boots. If their torn they need to be replaced. That was my issue.
