Sorry to revive an old post, but am very interested in going with the Fast Track w/IRS for a 68 Camaro convertible build.

I wanted to know more about the exhaust. I saw in some pics how the exhaust runs through the top of the IRS, but how do you run it behind the axle? The website mentions that a stock tank fits, but in some of the pictures in the build thread, it looks like you have to run a custom tank. Can you let me know what the options are? Thanks!

The build thread that you referenced is not a great example to look at in regards to your questions. That car had a complete custom chassis built for it with a lot of unique components and ideas.

When running the IRS on a 1st gen camaro, you can no longer run the stock tank. (you can run the stock tank with the solid axle 9" rear suspension) A custom tank would have to be built. Rick's Tanks or Rock Valley can both provide you with that end of the build for $1,000 - $1,500 depending on your motor's fuel pump requirements.

Here are a few good shots of the exhaust and fuel tank on a 66 Chevelle with the IRS. It is a different car, but similar idea on the tank and exhaust. The customer wanted the exhaust run on the outside of the frame rails on this car. You could also run the exhaust inside the frame rails and make a narrower tank.

Thanks for the update...glad to hear a tank is readily available (was planning on going with a Rick's tank already).

Still looking at all of my options...don't plan to start the project until next summer (car just arrived yesterday). Already have the wife on board with the LSA/4L85E. Hoping I can convince her that the full chassis with IRS is the way to go

P.S. Love your last picture!

Here's our next project....

That last picture is one of my favorites too. Go for the IRS. You won't regret it. Awesome ride combined with phenomenal handling.
