Upgrade your BMW’s performance with this high-quality 2.5-inch de-cat downpipe, designed specifically for the BMW 1 Series (F20/F21) and 3 Series (F22/F30) with the N13 1.6T engine (114i, 116i, 118i, 120i, 316i, 318i). This downpipe is engineered for maximum flow and performance, making it a perfect choice for enthusiasts looking to improve turbo response, horsepower, and exhaust sound.
