The Magnaflow Competition Series Exhaust System for the WRX and STI features a TIG-welded 409 stainless-steel construction with 76.2mm-diameter piping. Aside from the stamped steel flange at the down pipe end, the exhaust system utilizes slip-fit ends with clamps to secure the four pieces in place. The 76.2mm diameter is maintained throughout the length of the exhaust, up to the two mufflers at the end. The Magnaflow exhaust system produced an aggressive, growling exhaust note, touching on 95 decibels at 5,000 RPM at its loudest. This exhaust employed four massive 101.6mm dual-wall, slant cut tips for a bold look to match the sound. Power showed a slight improvement, with a 4.23 peak horsepower increase to top out at 281.77whp at 5,900 RPM. We found the most gains at 4,500 RPM and just after 6,000 RPM to redline.
