By merging the exhaust flow into a single, 3.5\" midpipe, backpressure is reduced and overall exhaust flow is improved. The factory BMW 335i midpipe uses a dual midpipe design which incorporates secondary catalysts which prioritizes noise control and mass production over performance and sound quality.
