Show original supplier description

The MAPerformance Stage 2 Upgrade Kit is a bolt-on performance solution for the 2015-2020 Subaru WRX, designed to maximize power gains with a single purchase. All components are fabricated in-house from 304 stainless steel, ensuring durability and resistance to corrosion. The kit features a catted downpipe with an integrated wideband O2 bung, 100% mandrel-bent 3" piping for the resonated cat-back exhaust with dual muffler outlets and twin 3.5" slash-cut tips, and a 3" diameter air intake with a direct-fit design that reuses factory connections and includes an MAF extension. This package also includes a custom MAP Stage 2 tune, with options for 91/93 octane or E30 fuel. With a 91 octane protune, expect approximately 310 whp and 330 wtq; on 93 octane, 322 whp and 336 wtq; and on E30, up to 345 whp and 355 wtq. This represents substantial increases over factory output. The kit is built to order, requiring approximately two weeks for production.
