New and improved thicker 321 stainless material!
New for 2012, this header now has 2mm thick pipes and 3mm thick collectors of 321 stainless steel. The preferred material for high temp applications, 321 stainless steel offers extreme resistance to high temperatures. Used extensively for turbo and aircraft applications, 321 stainless steel withstands temperatures in excess of 1650 degrees without losing its structural integrity. Flanges are 12mm 304 stainless steel.
This header is the result of 10 years of development at Small Car. It is designed to be as compact as possible for strength and to maximize ground clearance. It's designed to fit with the stock 1986 and later collector to cat pipe using the stock metal ring. 1985 and earlier Vans will need the later J pipe.
With an OE collector or "J" pipe, this will position a stock or aftermarket muffler just inside of rear valance, the correct spot to attach muffler to the Small Car mount.
Fits 2.2L engines 1990-1995 and all 2.5L normally aspirated Subaru engines in manual or automatic Vanagons. When used in a Syncro, the skid plate can be refitted.
Note: Does not fit the special low emission Legacy U5 2005- (the model with 5 oxygen sensors).
Two 44022-AA020 gaskets are recommended.
