The range of cast downpipes is designed to enhance gas-flow and heat management, increasing efficiency and performance gains. Standard OEM catalysts typically use 500-600 cells, while the race catalyst reduces this to 200 cells. This results in a freer-flowing catalyst, improving gas-flow and performance. - Cast downpipes improve gas-flow and heat management - Race catalyst features 200 cells for increased flow - Designed to increase efficiency and performance gains Specifications: - Pipe Diameter: 76.20 - Race Product: Yes - EMarked: No Kit comes with: - Milltek Downpipe-to-OE Cat-back Connecting Pipe - MSSE148 - Cast Downpipe with 200CPSI No Cell Race Cat - MSVAG06NC Vehicle Compatibility: - Seat / Cupra Leon Cupra 280 & 290 2.0 TSI (Non OPF/GPF Models) 2014-2017 - Seat / Cupra Leon Cupra 300 2.0 TSI (Non-OPF/GPF Models) 2018-2019 - Volkswagen Golf MK7 GTi (including GTi Performance Pack, Clubsport & Clubsport S models) 2013-2016 - Volkswagen Golf MK7.5 GTi (Non Performance Pack Models & Non-GPF Equipped Models Only) 2017-2018 - Volkswagen Golf MK7.5 GTi (Performance Pack Models & Non OPF/GPF Equipped Models Only) 2017-2018 - Volkswagen Jetta Mk7 (MQB) GLi 2.0T 2019 and Later
