Milltek Sport Large-Bore Downpipes are designed to improve both performance and sound. These downpipes feature a larger diameter compared to standard OEM parts, providing significantly more space for exhaust gases to exit the engine and pass through, which increases efficiency. The primary catalyst is removed from the exhaust system to create a freer-flowing exhaust, allowing the engine to operate more efficiently and increase performance. - Larger diameter than OEM downpipes for improved gas flow - Primary catalyst removed for enhanced exhaust flow - Designed to increase engine efficiency and performance Specifications: - Pipe Diameter: 70.00 - Installation Time: 3 to 3.5 hours (including removing OE system) - Race Product: Yes - EMarked: No Kit comes with: - LH Primary Cat Rep Downpipe - MSBM266 - RH Primary Cat Rep Downpipe - MSBM267 - GPF/OPF Bypass Section - MSBM304REP Vehicle Compatibility: - 2018 and later BMW 2 Series M2 Competition Coupe (F87)
