{"product_id":"bmw-135i-downpipe-back-race-exhaust-system","title":"BMW 135i Downpipe-Back Race Exhaust System","description":"The Berk Technology Exhaust System (BT1801-SMP-HPC) is a full race exhaust system engineered for the BMW 135i 2008 and up models. It features dual 2.5\" resonated midpipes that connect to a single 3\" Y-pipe, leading into a rear section with a muffler delete. The system is finished with dual 80mm dual wall tips and coated with 2000°F black ceramic for a more OEM appearance.\n\nThis exhaust system is the same one utilized on the Berk Technology 135i Time Attack racecar, highlighting its performance-oriented design. It removes the secondary catalytic converters in the midpipe, contributing to its lighter weight and increased flow. The dual 2.5\" tubing in the midpipe and the 3\" tubing leading to the dual 2.5\" Y-pipe in the rear section are all constructed for optimal exhaust gas velocity and minimal restriction.\n\nBerk Technology exhaust systems are known for their exotic pitch in the upper RPM range, allowing the driver to clearly hear engine communication. However, this system is not recommended for daily driven street use and is best suited for serious track competitors. The construction focuses on delivering peak performance and an aggressive auditory experience for demanding driving conditions.","brand":"Berk Technology","offers":[{"title":"Default Title","offer_id":52687121449272,"sku":"BT1801-SMP-HPC","price":1462.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660679410.webp?v=1784880561","url":"https:\/\/store.motormia.co\/products\/bmw-135i-downpipe-back-race-exhaust-system","provider":"MOTORMIA","version":"1.0","type":"link"}
