Stage 2 Performance Upgrade Kit

The MAPerformance Stage 2 Package is a comprehensive bolt-on performance solution designed to maximize the potential of the 2015-2020 Subaru WRX. By consolidating essential upgrades into a single kit, it simplifies the transition to a higher performance tier while ensuring component compatibility. Every fabricated piece is hand-made in the USA using 304 stainless steel and features 100% mandrel-bent tubing, fully TIG-welded and back-purged construction for long-term durability. The kit includes a 3-inch catted downpipe with an integrated wideband O2 bung, a resonated cat-back exhaust system with dual 3.5-inch slash-cut tips, and a high-flow air intake that reuses factory connections and includes a MAF extension. This setup is specifically engineered for the 2015-2020 Subaru WRX with a manual transmission. Please note that this package is not compatible with CVT models. Installation requires basic hand tools, though users should be prepared for the removal of factory exhaust hardware which may require penetrant or heat. The system is backed by the MAP Limited Lifetime Warranty against cracking, warping, or failing. For optimal results, a professional protune (91 or 93 Octane) is recommended to realize the full power potential of these hardware upgrades. An optional COBB Accessport V3 is available to facilitate tuning.
