The downpipes are designed to enhance turbo spooling by removing exhaust flow restrictions, resulting in immediate gains in horsepower and torque. These downpipes are constructed using T304 stainless steel tubes with CNC velocity stack flanges and TIG-welded joints with v-band flanges to ensure durability. Additionally, the factory O2 locations are retained with stainless steel bungs, and the downpipes are designed to fit the customer’s car like OEM downpipes. However, it is important to note that these downpipes are for off-road use only and can result in a check engine/service engine soon light.
