exhaust fumes inside cab! problem solved.

ya'll may remember my post about fumes inside my fastback. well, i had a very effective way to identify how exhaust gases flowed and wanted to share.
I had a friend drive my car at various speeds, while I waved a broom-stick around with a 6" string attached to the end of it. It was interesting to see how string (airflow) is very smooth 1 foot to the side of the car and how the flow actually rolls in and over the rear tailgate.
After identifying a spot where the flow doesn't go back into the car i rigged up a temp system...check it out.

Looks like half of a deep water fording kit.... You were getting exhaust fumes with an unaltered stock exhaust?

I can appreciate your hard work. I'm thinking that bottom of it is going to get crushed off road. It also sticks way up in the air. Couldn't you just just chop the exhaust off pre rear diff and 90 degree it towards the drivers side? Or, seal up your leaks better. Just my opinion, but it is a bit cheesy. I have probably done some mods that others dont care for, so please dont take offense.

My old willys m38a1 had a military spec deep water fording kit with something similar on the exhaust. It was made of a heavy pipe, though, coming up from the rear, not side.

You have to be careful with lighter weight exhaust tubing, as you could pull out the system off the hangers if it snags on something.

I don't know what would look more strange..... Waiving a broom stick around with a piece of string while someone else drives or the end result! Love the dedication though. We are all completely nuts. I'm in good company I see!

Did you try stuffing some towels down into the cornes where the fastback meets the body? That's all that should have been required.

Although I say just remove the fastback and run a bikini top

It'd look even better if you had a full roll cage! I just happen to know where one is

Sorry but that is just goofy. But don't let that sway you from the course. It will be less bling when it starts to rust, which should help lessen the shower of panties as you cruise around manhttan and the boroughs. I wish I had something more constructive to offer, but all I can think of is to try opening one of the dash vents or crack a window a tad to pressurize the cab a little bit. Or go with a better top.

Be careful someone doesn't scorch their hand or arm walking near it. You may even be liable if someone gets hurt in a parking lot after you just pulled up!!!

Im sure there is bound to be a more "subtle" way to keep fumes out of the truck. That cage is my favorite less the exo on 90 see Cvonc's truck
