{"type":"firestarter.listing","listing":{"id":"lst_bEcQK6j9","product_name":"APR CATBACK EXHAUST SYSTEM - 2020+ Audi RS Q8","category":"Catback Exhaust","description":"Our premium catback exhaust system is a full length T304 stainless steel exhaust system that's sure to turn heads! Cast flanges make a smooth transition from the factory turbo catalyst pipes into our downpipes and upgrade the size of the piping to 3\". High quality brushed T304 stainless steel adorns the system with TIG welding throughout. The piping is as straight and smooth as possible, with mandrel bends and minimal mufflers for maximum flow. Quad pipes exit the system into the exhaust tips and consist of dual 3\" valved exhaust paths and dual 2.5\" non-valued paths. This allows for multiple sound profiles depending on driving style. The RS Q8 is a monster and sounds absolutely menacing when under wide pen throttle. When the vales open, the fire-breathing twin-turbo V8 gets rowdy. Expect a deep and throaty roar that will send shivers up and done your spine as you're pinned to the back of your seat. And yet when you contain the beat and drive like a normal human being the ECU controlled valves close, reducing sound volume and drone. If you fight the urge to drive like a maniac, the exhaust will reward you with a pleasant low rumble that lets you know its there without upsetting the neighborhood. This is the ultimate exhaust system for the Audi RS Q8!\nFeatures:\n\nT304 stainless-steel construction\nFull system from the cats back\nArgon back-purged TIG welding throughout\nDual 3” mandrel-bent brushed tubing with dual 3” valved and dual 2.5” non-valved outlets\nUltra smooth Cast downpipe inlets\nDual exhaust valves\nBrushed-finished sound absorption mufflers\nRugged and precise mounting brackets\nOEM style no-compromise flex sections that won’t collapse, billow, and fail\nOEM style slip clamps\nPlug and play design\nLarger diameter piping compared to stock\nIn-house design with world-class manufacturing and quality control\nEasy to install\n\n \nYouTube Video: https://www.youtube.com/watch?v=N9eNsBVpVG0\n \nInstall Instructions: tl100160_rsq8_exhaust_web.pdf (goapr.com)","images":["https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_001.jpg?v=1699034847","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_036.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_002.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_003.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_004.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_005.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_006.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_007.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_008.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_009.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_010.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_011.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_012.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_013.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_014.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_015.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_016.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_017.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_018.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_019.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_020.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_021.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_022.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_023.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_024.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_025.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_026.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_027.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_028.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_029.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_030.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_031.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_032.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_034.jpg?v=1699035074","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0051_035.jpg?v=1699035074"],"price":3799.95,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:21.934Z"},"share_url":"https://firestarter.network/l/lst_bEcQK6j9","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
