{"type":"firestarter.listing","listing":{"id":"lst_oDNraor8","product_name":"ARM Motorsports 4.5\" Downpipe - VW/Audi MQB 2.0T (FWD)","category":"Downpipes","description":"\n\nHIGHLIGHTS\n\n\n• Increased Power and Torque• Massive 4.5\" Design• Direct Fitment\n\n• Largest GTI Downpipe\n\n• High Quality T304 Stainless Steel• Aggressive Exhaust Note\n\n  \nPROFILE\n\nThe ARM MK7 4.5\" GTI Downpipe is an essential upgrade if you're looking to get the most from your Gen 3 EA888 equipped GTI.  With it's full 4.5\" body, the ARM MK7 4.5\" Downpipe gives you unsurpassed exhaust flow and sound for your 2.0T.  Whether you are running the stock IS20, upgraded IS38, or hybrid turbo, the ARM 4.5\" Downpipe is the perfect downpipe upgrade to support any build.\n\n\n\n\n\n\n  The stock downpipe is built with a dense catalyst that hinders exhaust flow on your EA888 engine, causing higher back-pressure, increasing turbo lag and causing your turbo to work harder. Replacing your OEM downpipe with the ARM MK7 4.5\" GTI Downpipe will significantly improve exhaust flow, reducing the back-pressure generated by your turbocharger. The result of the increased exhaust flow is faster turbo spool, increased power and torque, and a remarkable improvement in exhaust note.\nThe ARM 4.5\" Downpipe doesn't just give you more power, it delivers an exhaust note that commands attention. Enjoy a rich, aggressive tone under acceleration, with no drone. This perfect balance of sound and performance makes every drive something to look forward to.   In addition, the improved exhaust flow will allow you to run increased boost targets found with Stage 2+ tuning software.  Attempting to run Stage 2+ tuning files over 25psi with the stock downpipe can put excessive stress on your turbocharger and is not recommended.  Most tuners require an upgraded downpipe to run their more aggressive tunes.  \n\n\n\n\n\n\n\nFor the ultimate combination of power, sound, and performance, pair the ARM MK7 GTI 4.5\" Downpipe with the ARM GTI Exhaust. Together, these upgrades create a system designed to maximize airflow, performance, sound and delivers an unforgettable driving experience.\n\n \nCONSTRUCTION\nMade of TIG welded T304 grade st","images":["https://cdn.shopify.com/s/files/1/0024/4898/2060/files/3V0A0836_5000x_ffc7e380-1268-4e8c-a523-3414b3482bb6.webp?v=1773761061","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/4.5Design_5000x_1da7f2e8-9792-4140-b505-5f433f870fc0.webp?v=1773761061","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/3V0A0827_5000x_29d52880-fdfe-4aa4-8b7c-291cd1bb56a5.webp?v=1773761061","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/3V0A0828_5000x_1aa77610-3ec2-4225-bfff-c2be5691a8ff.webp?v=1773761061","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/3V0A0829_5000x_a5d5d31e-5055-41d5-8ecc-b020c6ff26cf.webp?v=1773761061","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/3V0A0830_5000x_f14de051-b2b7-4e83-98eb-4e9ab0a59dac.webp?v=1773761061","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/3V0A0832_5000x_6ba94bc9-748e-4bb5-9cd4-982f1f228afb.webp?v=1773761061","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/3V0A0834_5000x_3d194294-9527-4340-bafb-3f3d134716d3.webp?v=1773761061","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/3V0A0835_5000x_8d936ee1-e89f-4767-b3df-6a6a3f372d1d.webp?v=1773761061","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/3V0A0838_5000x_5b561249-7606-415d-9a1e-f7c6278b495e.webp?v=1773761061","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/Title_5000x_47a1b458-d136-4aea-a292-e9f532586c7e.webp?v=1773761034"],"price":497,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:21.287Z"},"share_url":"https://firestarter.network/l/lst_oDNraor8","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
