I like the 45 degree exit as shown.

Likely.@PabloCruise so it will work for those of us that have not flipped our rear springs and run sub 33' tires? Please help me understand, but the way I read it is you are trying to solve for a problem that is likely isolated to only people that have oversized tires AND flipped springs? Which I would think would be a very small number.
Thanks for the comments.@65swb45 brings up a good point, and reminded me of what modifications I had to do to a new exhaust that was installed when I initially purchased my 40. In the photo below, you can see how the mechanic had the exhaust run a little more than 45 degree out the right rear corner.

However, with the top off, this configuration sucked too much exhaust fumes back into the drivers/passenger area.....so I took it to my local exhaust guy, and he knew right away what the problem was. Thus, he cut and ran it straight out the right rear side, just behind the wheel. This took care of most, if not all of the exhaust fumes.

Thanks Claudia. No way to we want to run straight out the back.running the pipe straight back will pull all the exhaust right back in - it HAS to go out behind the rear tire
don't ask me how I know
[also, the closer the exhaust comes out behind the tire, the more hassle the emissions guys will give you, as they will have to finagle the sniffer cone on with the tire in the way . . . ]
See if these help.Thanks for the comments.
You are running 32s?
Do you think a person could fit 35s on there w/o hitting the pipe?
Is your tailpipe exiting out the side as far back as possible? I need a minute to crawl through your build thread...
The side exit looks to work for those that leave their rear axle housing where Mr. T intended it to be...@PabloCruise so it will work for those of us that have not flipped our rear springs and run sub 33' tires?

For clarification: Tire - 32x11.50R15, Rim - 15" OEM modified to 9" wide, Springs - OME medium CS001R, Shackle - OMEGS9
Here’s mine. Stock exhaust. Stock mounting bracket in the stock location. Springs fully extended. Mid 66 build date.The side exit looks to work for those that leave their rear axle housing where Mr. T intended it to be...
Agreed - I don't know of too many other folk who have moved the rear axle back.

Correct that I have 31's, was thinking about going bigger after I get my PS installed but maybe not! This exhaust is perfection and I don't want to mess with it. The setup that you have configured fits stock FJ40's and people that modify their suspension know that other things are also affected. Just my opinion, but sell the stock exhaust and those of you with modified 40's can make the necessary changes to fit your specific mods. The people that need to update can post what changes they made and how they made them to help others. I think all of us who actually work on our trucks knows that nothing is really ever "bolt on!"
I have not been able to get my 40 out of storage yet, I have only managed one trip around the block. When it has been warm here, it's been raining. A huge storm is actually rolling through as I type this. Still plan to post up some sound for you all, exhaust sounds awesome
I second selling the stock exhaust and let folks that have other setups tweak it to fit.Correct that I have 31's, was thinking about going bigger after I get my PS installed but maybe not!
