{"type":"firestarter.listing","listing":{"id":"lst_s3EOoFv1","product_name":"APR CATBACK EXHAUST SYSTEM - GTI (MK8)","category":"Exhausts","description":"The APR Catback Exhaust System personalizes your vehicle's looks, sound and performance. Beautifully hand-crafted T304-stainless-steel components adorn the system with stunning TIG-welding throughout. Our straight-through brushed-finished mufflers smooth the exhaust note to a deep growl, without adding restrictions or rasp. Strong high-quality bracketry and OEM-style clamps hold the system steadily in place, making the install or removal a snap, and fitment simple, yet precise. 3\" (76mm) mandrel-bent exhaust paths provide an ultra-smooth path, steadily feeding exhaust gasses out of the dual 2.5\" (63.5mm) exit pipes, while looking tidy from under the rear bumper. Finally, removable 4\" (102mm) polished slash-cut exhaust tips finish the system, adding a classy motorsport-inspired touch to the rear of the vehicle.\n\nFeatures:\n\nT304 stainless-steel construction\nTIG welding throughout\nSingle 3\" (76mm) to dual 2.5\" (63.5mm) mandrel-bent brushed tubing\nPolished 4\" (102mm) slash-cut exhaust tips (removable)\nCompatible with APR single and double wall tip options in various colors and finishes\nBrushed-finished sound absorption muffler / drone eliminating Helmholtz resonator\nRugged and precise mounting brackets\nOEM style slip clamps\nPlug and play design\nLow-profile design, suitable for lowered vehicles\nLarger diameter piping compared to stock\nLarger diameter tips compared to stock\nPiping cross-sectional area up to 60% larger than stock\nWeighs 9% less than stock\nIn-house design with world-class manufacturing and quality control\nEasy to install\n","images":["https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0047_001.jpg?v=1705102259","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0047_019.jpg?v=1705102260","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0047_020.jpg?v=1705102262","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0047_002.jpg?v=1705102261","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0047_003.jpg?v=1705102263","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0047_005.jpg?v=1705102263","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0047_007.jpg?v=1705102262","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0047_009.jpg?v=1705102260","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0047_012.jpg?v=1705102260","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0047_014.jpg?v=1705102264","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0047_015.jpg?v=1705102259","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/cbk0047_021.png?v=1705102258"],"price":1099.95,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:21.941Z"},"share_url":"https://firestarter.network/l/lst_s3EOoFv1","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
