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?
