Welcome Jrob... we'd love to hear more about you and your car? photos? etc.. which might help to answer some of your questions...

Sounds like you have a solid rear axle of some type? Headers or stock type manifolds?

There are basically two issues: 1) getting from your exhaust manifolds down to the chassis, and 2) clearing the rear axle. There are probably too many variable (how low is the car? which exhaust manifolds or headers? etc) to identify a specific off the shelf exhaust system IMO. Most updated cars have to get at least 'partial' custom exhaust. Identify all your parts and perhaps someone can provide a more exact response?

With inboard springs and a 22 gallon tank, it's certainly going to require custom exhaust. There won't be an off the shelf solution to be sure.

With the inboard springs, there's really no way to run tailpipes all the way to the bumper without putting them under the tank. And that's going to be difficult at best. Tailpipe exit in front of the rear wheels is going to be easier but it's going to leave much to be desired IMO.

If you had mounted the springs "pocket kit" style and used a 16 gallon tank, designing and building an exhaust system would have been much easier. Still with some challenges because it's a wagon.

My 55 has a mini tub and a centered 16 gallon tank with 2 1/2 tailpipes, its all custom made by a local muffler shop.

I recently needed exhaust for a '56 Chevy convertible. I found 2" aluminized exhaust with turbo mufflers at Summit for $659.99 plus tax, plus truck freight shipping charges.

I then went to a local speed shop that does exhaust work. I got a 2.25" aluminized exhaust with turbo mufflers, new copper collector gaskets, new exhaust hangers, two chrome tips, plus tax, plus labor for $639.69. They did all the work while I sat back and watched.

It sounds like with the way your car is modified that custom exhaust installed by a muffler shop would be your best route to go.

Unless the car is stock underneath I would definatly go with a local custom system.

I've never considered doing my own installation of exhaust. I'd rather pay a pro, get a great custom system that's all tucked up nice and be done with it. It's easy to tell them what mufflers you want and they do it. I don't see much difference in price.

I hated exhaust work until I got a 9000k two post lift in my shop. I bought a dual system on EBay for Dads 66 Mustang for $199 on EBAY and installed it about 12 years ago . It was a cake walk and I would do it again. However, on a modified car I would not recomend it.
