{"product_id":"76mm-performance-downpipe-w-300-cell-cat","title":"76mm Performance Downpipe w\/ 300 Cell Cat","description":"Maximizing engine performance begins with effective heat management, especially in turbocharged applications where extreme heat can hinder ECU mapping. The HPA MQB (AWD) 1.8T \u0026amp; 2.0T Downpipe addresses OEM design limitations, such as restrictive 63mm diameters and varying angles that create back pressure. This HPA downpipe, proudly manufactured in Canada, is fabricated from .063wall T304L stainless mandrel tubing. It features precision TIG welding with Argon back purging for a clean interior and exterior finish.\n\nThe flex couplings utilize an internal stainless steel interlock liner for smooth flow of high-temperature exhaust gases. This \"Street\" version is equipped with a 300 Cell High Flow metal catalytic converter, similar to those used on HPA's high-performance twin-turbo vehicles. The design removes the factory catalytic converter directly from the turbo to increase exhaust flow and reduce back pressure.\n\nKey features include a 76mm diameter, full stainless steel construction, integrated laser-cut\/CNC-formed heat shield, and an integrated OEM upper turbo support bracket. It also incorporates a reducer for OEM cat-back compatibility and includes an O2 harness extension.\n\nVehicle Fitment:\n- 2015-2019 Volkswagen Golf R MK7 \/ MK7.5\n- 2015+ Volkswagen Sportwagen \/ Alltrack MK7 (AWD only, Requires an exhaust adapter.)\n- 2014+ Audi S3 8V\n- 2014+ Audi A3 8V\n- 2016+ Audi TT 8S\n- 2016+ Audi TTS 8S (Mid pipe length must be modified to fit)","brand":"HPA","offers":[{"title":"Default Title","offer_id":52688700932408,"sku":"HVA-253-STREET","price":879.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663181565.webp?v=1784893185","url":"https:\/\/store.motormia.co\/products\/76mm-performance-downpipe-w-300-cell-cat","provider":"MOTORMIA","version":"1.0","type":"link"}
