Show original supplier description
The Supersprint 523111 is a performance-oriented downpipe meticulously crafted to replace the factory catalytic converter in specific BMW vehicles. It features an oversized 76mm pipe diameter to facilitate improved exhaust gas flow. Supersprint is renowned for its dedication to quality, innovation, and performance, with a history dating back to 1955. Their exhaust systems are known for their premium materials and precision fitment, aiming to increase engine power and refine the car's sound. This particular downpipe is compatible with a range of BMW 3 Series (F30/F31 LCI) and 4 Series (F32/F33/F36 LCI) models equipped with the 2.0T B46 engine, typically from 2015 onwards. Specific fitment includes the 330i, 330iX, 430i, and 430iX variants, and it is also noted to work with models equipped with a valve system. Always verify fitment with your specific vehicle details before purchase.
