Show original supplier description
The Scorpion Exhaust SBMX102 is a 5-inch, 200-cell sports cat downpipe, engineered to replace the OE catalytic converter for BMW vehicles equipped with B58 engines. Crafted by Scorpion Exhausts in the UK, this component is built to enhance both performance and reliability through improved gas flow. The construction process emphasizes precision and advanced technology to provide unmatched gas flow, which can lead to enhanced throttle response and increased BHP. This downpipe is specifically designed to maximize flow capacity and unlock peak performance for the B58 engine. This particular downpipe is noted for its 5-inch diameter and a 200-cell high-flow sports catalyst. It is compatible with a range of BMW models, including the M140i (F20/F21 2013-2018) and other vehicles with B58 engines such as the 340i, 440i, and 540i. The product replaces the original equipment catalytic converter to allow for greater exhaust efficiency.
