The AMR un-equal length header is made out of 304 U.S.A. stainless. Each tube is mandrel bent to ensure smooth flow. It is equipped with AMR's custom CNC 1/2 thick flanges to ensure no warping. Just like all AMR Products, they are made in-house! AMR Headers are the only company which manufacture a 2 inch tube diameter header for the Subaru community.
In-House testing has proven on a Subaru STi, with proper tuning, AMR has seen an increase of 20-30wtq and 20-30whp over standard/factory exhaust housings/headers.
***Note: The unit comes with a ceramic base 1500 degree coating for no charge. We are not responsible for flaking and scratches on complimentary coating. We do offer a thermal 2000 degree coating but there will be an additional charge.
This header is hand TIG welded, not robotically welded like many overseas manufactures.
Warranty: This item comes with a 1 year warranty against cracking, fitment and warping!
