{"type":"firestarter.listing","listing":{"id":"lst_Be_-uro8","product_name":"AWE SwitchPath™ Catback Exhaust for BMW F8X M3/M4 - Chrome Silver Tips","category":"Exhaust","description":"Unified design for OPF euro and non-euro spec cars, 50-state legal Cat Back design, precision-engineered X-pipe to unlock a clean S55 tone, retained M-Sport button functionality, 3” CNC mandrel-bent configuration, max gains of 12 hp and 16 lb-ft of torque at the wheels and signature AWE 102mm double-walled, slash-cut tips in Chrome Silver or Diamond Black. Throw in a No Check Engine Light Guarantee, Perfect Fitment Guarantee and Lifetime Warranty and you've got the only real option for your S55. Minimal bends, maximum flow, and push-button attitude. The SwitchPath™ Exhaust is a true Cat Back configuration comprised of 3-inch and 2.5-inch U.S.-sourced T304L stainless steel, a precision x-pipe, and a valved SwitchPath™ muffler tuned specifically for the S55. Beginning after the secondary catalysts, the precision X-pipe immediately helps smooth the S55 of its infamous rasp, allowing the tone to be further refined by the bespoke muffler in the rear. The closed valve experience: When the valves are closed, the SwitchPath™ Exhaust produces a refined, aggressive howl while remaining full-bodied and powerful – no congested, metallic sounds here when on the throttle. At cruising speeds, interior acoustics are close to stock. AWE SwitchPath™ tech also responds perfectly to the many transmission settings and shift points in DCT vehicles.\n   Features\n\n\nProudly engineered, designed, and manufactured in-house at AWE\nSwitchPath™ utilizes factory valving and retains M-Sport button functionality\nMax gains of 12 hp and 16 lb-ft of torque at the wheels\n3” CNC mandrel-bent Cat Back configuration\nNo Check Engine Light Guarantee\nUnified design for OPF euro and non-euro spec cars\nPerfect Fitment Guarantee\n50-state legal Cat Back design: sick sound with all catalysts intact\nPrecision-engineered X-pipe to unlock a clean S55 tone\nTip options include 102mm double-walled, slash-cut tips in Chrome Silver or Diamond Black\nHandcrafted from U.S.-sourced .065\" wall T304L stainless steel\nFeaturing t","images":["https://cdn.shopify.com/s/files/1/0024/4898/2060/files/96962ce6a26ce2dc8873272c871ab089.jpg?v=1752767007","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/77b41cfe34fd3a476a91f03448d2bcdd.jpg?v=1752767007","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/c2e0edac397ab89748c026fec63e174d.jpg?v=1752767007","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/5c3f12a8761e7fc47f0be2468b9603b1.jpg?v=1752767007","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/93161390729289611d42a9e8c2954840.jpg?v=1752767007","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/2cef857bd64dce6c520d335602961e54.jpg?v=1752767007","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/f829fed5a2129e0aca9afeced4f6da78.jpg?v=1752767007","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/eb872e00a44487564f4eb52fd0f25b5d.jpg?v=1752767007","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/fec9697ddbe567c4c141674ef509de28.jpg?v=1752766983"],"price":2775,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:26.872Z"},"share_url":"https://firestarter.network/l/lst_Be_-uro8","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
