{"product_id":"3-00-inch-catted-downpipe","title":"3.00-Inch Catted Downpipe","description":"The Mishimoto Catted Downpipe is engineered to replace the restrictive factory pipe in your 2015+ Subaru WRX, offering significant improvements in horsepower, torque, and engine response. Designed as a one-piece unit from 304 stainless steel, it ensures uninterrupted exhaust flow. The 3.00-inch inner diameter piping and the 3.5-inch to 3.0-inch transition out of the turbo outlet facilitate smoother gas flow under acceleration and boost.\n\nConstruction details include a 3\/8\" thick, CNC-machined stainless steel four-bolt flange for a secure connection, new studs for the turbine housing, and a stock gasket for the turbo outlet. An additional wideband oxygen-sensor bung is conveniently located for aftermarket sensor installation.\n\nMishimoto has conducted dyno testing to verify the performance gains. With a tune, the catted downpipe alone provides up to 57 WHP and 52 WTQ. When paired with the Mishimoto Performance Air Intake and a tune, these gains increase to up to 73 WHP and 64 WTQ, utilizing 93 octane fuel on a 6-speed transmission. Expect significant torque improvements across the entire powerband, particularly in the low end.","brand":"Mishimoto","offers":[{"title":"Default Title","offer_id":52689171120440,"sku":"MISMMDP-WRX-15CAT","price":782.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687390116.webp?v=1784902947","url":"https:\/\/store.motormia.co\/products\/3-00-inch-catted-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
