The aFe Twisted Steel long-tube header for 2002–2019 Subaru Impreza WRX/STI and Legacy turbo models is constructed from 304 stainless steel with mandrel-bent tubing and laser-cut flanges for a durable, leak-resistant seal. Optimized tube lengths and 100% TIG welding aim to improve exhaust flow and strength while maintaining compatibility with the factory exhaust system without the need for modifications.
