Pre-bent exhaust system - any options?

[davepl]

For my '70 402 Longhorn restoration one non-stock alteration I'm going to indulge is either an aluminized or stainless exhaust system, ideally mandrel-bent.

I'd like to run Dynomax mufflers because I have a set on my other project and like the sound (quiet at idle and drone-free), so optimally I'd find a pre-bent pipe set and either discard the indluded mufflers or get a system without mufflers.

The only complete system I've found is one from LMC, but its not for the longhorn so would wind up too short for my truck anyway.

I could just haul it to a muffler shop, but I'd like smooth mandrel bends and don't know of any shops that can do that.

Does anyone know of a pre-bent kit?

Failing all of that, I could buy pipe and J and U bends and weld it up myself (I'm a novice, but can handle that much). If you've had any experience with a "make it yourself" kit that would fit our trucks, please let me know that as well!
