{"product_id":"76mm-downpipe-w-high-flow-cat","title":"76mm Downpipe w\/ High-Flow Cat","description":"The HPA Motorsports 1.8T \u0026amp; 2.0T Downpipe is a performance-oriented exhaust component designed to replace the restrictive factory downpipe on various Audi models. The OEM downpipe's smaller diameter, catalytic converter, and varying angles contribute to increased back pressure and force the turbo to work harder, generating excessive heat. This HPA downpipe addresses these limitations by increasing the diameter to 76mm and removing the factory catalytic converter, promoting improved exhaust flow and reduced back pressure directly off the turbo.\n\nConstructed from durable T304L stainless steel with a .063 wall thickness, this downpipe features precision TIG welding with Argon back purging for both internal and external clean welds. It is proudly manufactured in Canada. The assembly includes a CNC-formed hanger and laser-cut flanges for a precise fit to the chassis, capable of withstanding high thermal conditions. This model includes a 100-cell high-flow catalytic converter and a reducer to ensure compatibility with the OEM cat-back exhaust system. Factory O2 sensor placement is retained, and the design offers substantial weight savings over the stock unit.\n\nVehicle Fitment:\n- 2009 - 2016 Audi A4 B8 \/ B8.5 (LHD Only)\n- 2008 - 2016 Audi A5 B8 \/ B8.5 (LHD Only)\n- 2009 - 2016 Audi Q5 8R (LHD Only)","brand":"HPA Motorsports","offers":[{"title":"Default Title","offer_id":52688701882680,"sku":"HVA-252-STREET","price":549.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663693406.webp?v=1784893206","url":"https:\/\/store.motormia.co\/products\/76mm-downpipe-w-high-flow-cat","provider":"MOTORMIA","version":"1.0","type":"link"}
