Saw something very strange yesterday. A 10.5 outlaw car running 4.5's @160 1/8, but the strange part was the exhaust downstream of the turbos was made of aluminum. I asked the guy if he had had problems with this & he said it was new so he couldn't really answer the question. The car had done several passes w/o problems. Probably 4-5" tubing. I would not think this was anywhere near an option even on a drag car with exhaust temps (probably about 750C) well above the danger point of about 230-240C.

Anybody else ever try or see this?

Has anybody ever seen aluminum exhaust? I've seen Aluminum down pipes on racecars that dont see street duty, but Im wondering how an aluminum exhaust would hold up maybe from the downpipe back. If anybody has pics of anything like this post em up!
