exhaust system for BD with usdm wrx swap?

[striker]

What to do?

A friend of mine had told me that I would need to get a downpipe for a WRX and a catback exhaust system for the BD/GT. Is this correct? Whether I am wrong or right... Can anyone help me out here?

Links to aftermarket parts involving this subject would be great too.

I'd go with aftermarket WRX up and down pipes, a high-flow cat, and then have a (good) local exhaust shop custom do the rest with a quality muffler.

Use a full wrx exhaust and have the hangers modified. If the length is wrong, just have an exhaust shop fab you up a custom mid-pipe.
