{"product_id":"sports-series-resonated-mid-pipes","title":"Sports Series Resonated Mid Pipes","description":"The Evolution Racewerks Sports Series Resonated Mid Pipes are specifically designed to enhance the performance of S58-powered 2020+ BMW X3M and X4M models. These mid pipes directly replace the factory's restrictive resonators, incorporating high-flow resonated units to improve exhaust flow, boost throttle response, and increase torque delivery. The engineering goal is to achieve measurable performance gains while maintaining a refined, near-OEM exhaust tone, making them suitable for enthusiasts seeking improved performance without excessive noise.\n\nConstructed entirely in-house in the USA, these mid pipes feature robust 304 stainless steel tubing that is mandrel-bent for consistent diameter and unrestricted flow. The construction is 100% TIG-welded for superior strength and craftsmanship, complemented by precision CNC-machined stainless steel flanges that ensure a perfect fit and reliable seal. The design retains the factory H-crossover configuration, which has been extensively tested and chosen for its effectiveness in reducing interior drone, equalizing exhaust pressure, and improving low-end torque characteristics, mirroring BMW's own optimal design choice for drivability and sound quality.\n\nKey features include an increase in maximum horsepower potential, a stronger initial torque curve for faster acceleration, and quicker turbo spool for noticeably improved throttle response. The resonated design offers a quieter, refined tone while still increasing exhaust flow, making it ideal for daily driving or complementing aggressive aftermarket components.","brand":"Evolution Racewerks","offers":[{"title":"Default Title","offer_id":52687977513272,"sku":"BM-EXH025S","price":1046.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664708380.webp?v=1784888420","url":"https:\/\/store.motormia.co\/products\/sports-series-resonated-mid-pipes","provider":"MOTORMIA","version":"1.0","type":"link"}
