Manufactured from high quality T304 stainless steel with handmade TIG welds, these downpipes will bring an average gain of 34hp on a stage 1 engine and a particularly aggressive sound. With a high flow structure and thermal insulation to reduce heat radiation by 50%, these downpipes clearly represent the best value for money on the market.
