Does a 3" downpipe do much when it's going into the smaller catback exhaust system? It's indicated above that not all of those SEMA Fiestas had the 3" pipe all the way back. Also I'm wondering if a 3" pipe is really needed for a 1.6L engine. Wouldn't 2.5" be plenty for the amount of air being moved?
