So....

My headpipe rusted away last fall, just before I put the Dart up for the winter.
Now's my chance to upgrade the stock exhaust setup.

What are my options (besides increasing the pipe diameter)?
Here are the ones I know of so far:
- Dutra Duals
- Dual - Dutra Duals
- Clifford Shorty Headers
- Hooker Headers

Are there other header systems I'm missing from this list? I know that Mister Twister and AussieSpeed both have designs in the works, but they are not currently available.
