AMS Performance INFINITI Q50 Q60 VR30 Red Alpha Full Downpipes AMS-ALP.28.05.0002-1

The Red Alpha 3" Full mandrel bent downpipes are the best performing and most durable on the market. During testing our shop Q60 with our Red Alpha Full Downpipes, and Red Alpha Tune, our Engine Calibrators saw 20 horsepower gains over our lower downpipes and no CEL's! The power came on earlier and the twin turbos spool-up was significantly improved. The long gradual transitions within the mandrel bent pipe section allows exhaust gasses to maintain velocity without a buildup of back pressure inside of the system. We were able to design a superior product because of our superior engineering.
