Ahhh SVO ! OK got it. Good idea then. Would running the SVO pipe along side the exhaust pipe do the job? Naturally you wouldn't want it ot get oo hot. Possible running it through some stancions or stand-offs and let the hot Exhaust pipe physically trasnfer heat to the tube(pipe) carrying the SVO.

Have you had good success with SVO in your truck?
