This sport muffler system is crafted for maximum horsepower gains in a lightweight design, featuring a straight-through, polished muffler with unobstructed flow. The system utilizes 3.00\" tubing and is finished with twin 80mm dual-wall polished tips that complement the vehicle's original aesthetic.\n\nConstructed entirely from stainless steel and meticulously hand-assembled with TIG welding, this exhaust system ensures durability and longevity. It produces a deep, authoritative exhaust note with exotic undertones during aggressive acceleration. The \"street performance\" designation indicates a balance between an aggressive tone and daily drivability, avoiding excessive loudness.\n\nInstallation is designed to be straightforward, as all Berk Technology exhaust systems are 100% bolt-on, utilizing factory mounting points. No special tools or vehicle modifications are required for fitting. This exhaust system is explicitly designed to support both twin-turbo N54 and single-turbo N55 engines found in the BMW 135i variants.\n\nThe BT1801-M is specifically designed for the BMW 135i models in the E82 and E88 chassis from 2008 onwards. This includes compatibility with the N54 and N55 engine configurations, making it a direct fit for these performance-oriented BMWs.","brand":"Berk Technology","offers":[{"title":"Default Title","offer_id":52687121875256,"sku":"BT1801-M","price":652.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661170642.jpg?v=1784880567","url":"https:\/\/store.motormia.co\/products\/berk-technology-axle-back-exhaust-system","provider":"MOTORMIA","version":"1.0","type":"link"}
