{"product_id":"milltek-sport-bmw-g8x-large-bore-downpipe-and-de-cat","title":"Milltek Sport BMW G8X - Large Bore Downpipe and De-cat","description":"\u003cp\u003eUnlock the full performance potential of your BMW G8X M3, M4 or M2 (G87) with the Milltek Sport Large Bore Downpipe and De-cat. Fabricated with a significantly larger bore than the OEM downpipe, this upgrade dramatically improves exhaust gas evacuation from the S58 engine, reducing back pressure and increasing efficiency.\u003c\/p\u003e\u003cp\u003ePaired with the catalyst bypass pipe, this system removes any restriction to exhaust flow for maximum performance gain. The result is improved throttle response, enhanced mid-range torque, and a dramatic increase in exhaust sound — particularly noticeable when combined with a Milltek Sport cat-back or axle-back system.\u003c\/p\u003e\u003cp\u003eAvailable in two bore sizes (102mm and 3\"), this downpipe is a race product designed for track use and should be paired with an appropriate ECU remap. Manufactured from 304L aircraft-grade stainless steel and made in the UK.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFitment: BMW M3 G80\/G81 (2020+), M4 G82 (2020+), M2 G87 (2023+) — OPF\/GPF \u0026amp; Non-OPF variants\u003c\/li\u003e\n\u003cli\u003ePipe diameter: 76.20mm (3\")\u003c\/li\u003e\n\u003cli\u003eRace product: Yes\u003c\/li\u003e\n\u003cli\u003eFitting time: 3–4 hours\u003c\/li\u003e\n\u003cli\u003eMade in the UK\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSKU: SSXBM1271\u003c\/p\u003e","brand":"Milltek","offers":[{"title":"Default Title","offer_id":58335694291328,"sku":"SSXBM1271","price":1246.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0720\/7557\/5573\/files\/SSXBM1271_1.jpg?v=1782477690","url":"https:\/\/stringtheorygarage.com\/products\/milltek-sport-bmw-g8x-large-bore-downpipe-and-de-cat","provider":"String Theory Garage","version":"1.0","type":"link"}
