{"product_id":"alpha-performance-r35-gtr-wide-mouth-race-downpipes-90mm","title":"Alpha Performance R35 GTR Wide Mouth Race Downpipes 90mm","description":"The AMS Alpha Performance R35 GTR Widemouth Downpipe Upgrade is designed to deliver significant performance improvements for your Nissan GT-R. With its robust 90mm cast stainless steel construction, this upgrade optimizes exhaust flow, leading to substantial horsepower increases throughout the powerband and faster turbo spool-up.\n\nConstructed from 100% 304 stainless steel with 1\/2\" thick flanges, these downpipes are built for durability and reliability, surpassing welded alternatives that can be prone to cracking. The 90mm (3.5”) primary pipe enhances performance by improving turbo spool time and throttle response. Precision TIG welding ensures an exceptional fit and finish, while the cast inlet and outlet geometry is optimized for smooth exhaust flow and reduced backpressure.\n\nBeyond performance, these downpipes enhance the driving experience with a refined exhaust note that is throaty and aggressive at wide-open throttle, yet subtle and unobtrusive during idle and cruising. They offer stock-like fitment with no chassis clearance issues and bolt up to the stock mid-pipe or most aftermarket exhaust systems, providing a straightforward yet transformative upgrade.\n\nKey features include big horsepower increases, improved turbo spool and throttle response, and a pronounced exhaust note. The package includes two 90mm Alpha Cast downpipes, downpipe bracket hardware, and gaskets for the connection to the mid-pipe. This product is compatible with 2009+ Nissan R35 GT-R models equipped with the VR38DETT engine.","brand":"AMS Performance","offers":[{"title":"Default Title","offer_id":52689677812024,"sku":"ALP.07.05.0001","price":969.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/684561402.webp?v=1784909059","url":"https:\/\/store.motormia.co\/products\/alpha-performance-r35-gtr-wide-mouth-race-downpipes-90mm","provider":"MOTORMIA","version":"1.0","type":"link"}
