The SEMA show is a place to see the latest parts, and also some of the newest car creations from the best builders in the industry.    We spoke with Richard Waitas to learn more about the winning philosophy of MagnaFlow and how their association with people like Chip Foose, Arlen Ness, Mario Andretti, Richard Petty, and more impacts the parts they sell and the enthusiast's experience when using MagnaFlow parts.    We also got the brief tour of the stunning Foose Pantera on display in the booth.   V8TV 2015 SEMA coverage presented by ARP.
