The AMR equal length headers for Subarus are built from 100% 304 USA stainless steel. The massive 2in pipes on these headers are mandrel bent to ensure the smoothest flow possible. Equipped with 1/2in thick flanges to prevent warping and a ceramic base 1500 degree coating these headers are made to handle the heat from your Boxer engine. With increases of up to 20-30WHP and 40 ft /lbs of torque when tuned over the stock headers, the AMR equal length headers are guaranteed to provide you with the performance you need. The AMR equal length headers are also hand TIG welded to provide maximum durability. Due to the equal length design, the signature Boxer rumble will be lessened, but you will grow to love the aggressive sound the EL headers make.
