I'm sure you are already done but ah well i will post it anyhow.

A few months ago, I think it was HCI mag had this Integra with a huge custom turbo job. Anyhow the wastegate pipe was actually plumped into a 4 cycle motorcycle muffler than vented to the atmostphere. He ended up cutting a hole in the bumper just aft of the driver side front wheel to sitck out the tip of the muffler. The way it was done actually looked VERY pleasing to the eye and until I read the article I actually had no idea it was a muffler tip.

I think I still have the mag, and although I don't have a scanner I could take pics with my digital camera if you like, it has some good detailed pics of this setup i just described.
