Driving without rear window

I just got my soft top recently and I have been experimenting with it a bit. I have a 2dr JK. I really like the ease of opening the front portion without taking down the whole top.

The issue is without opening any of the rear windows it is a little loud and windy. I tried it 3 different ways. With all the windows out, with just the side windows out, and with just the rear out.

I'm not a fan of having the side windows out, with or without the back window. It seems to take some of the stability out of the back and the sides in the back flap around a lot. It also seems a little windier.

My favorite is just the top open and the rear window out. The issue is that I have heard that this is bad and pulls exhaust back into the cabin. Is this true? Is there any way to avoid it without opening more windows?

I ran like that for awhile in the spring, before just taking all the windows out and leaving them out now. Never had any problems. I did it with glass windows rolled down mostly, but sometimes with them up. Mostly, I had the top all the way closed, the front windows rolled down and either all 3 windows out or just the rear out.

I don't know if I lost some brain cells from the C02, but I am certain I didn't die.

Try to take all 3 rear windows out, take the top down (or better yet, off), then take the doors off. This is the way a Jeep should be...that way there is ABSOLUTELY no window position problem!

Driving with only the back window out will suck in auto exhaust and can elevate carbon monoxide levels in the blood.

If you want to drive with the back window out or down, open at least one side window or the Sunrider top to provide positive ventilation and keep out the fumes.

I have a hard top, but freedom tops off, all 4 windows down, and back window open works for me. I haven't smelled any exhaust or passed out behind the wheel yet.

I drive with back window out for months out of the year...never had a problem. Sometimes, on a calm day, or with wind from behind, it will blow a bit of the exhaust smell inside while you stop at a light or something but...once your driving again it clears up...never felt any ill effect from it.

Just too many exposure options to choose from & how do I keep my hat + jacket + tools + dog in back from disappearing. Nice problems to have on a gorgeous day.

LoL! Well...a buttoned up soft top ain't going to protect anything! I'm going to fab a deck enclosure for mine. From back of seats to the tailgate....need a trunk!

Back window out, windows down should not be a problem. We do it and don't experience any issues. With that said we are a 4 dr.

I've been working on waterproofing my rear area in my 2dr with the Tuffy Security Enclosure installed, using caulk/flexseal to waterproof the places where the trunk meets the carpet, then waterproofing the carpet itself (I know, I know- take out the carpet and bedline it, but I like the added insulation for winter and sound quality of sub with carpet inside trunk). This way I can use the soft top with no rear windows as soon as winter is all over and not worry about rain soaking everything in my trunk, then I just flip back the sunrider top when I drive.

Ya this is what I was planning on. Sunrider and back window open, with the rest closed.

I love having the whole thing down. This is mainly for my commute. I have a 30 minute commute to work on the highway.
