New and improved thicker 321 stainless material! 7/2012
New for 2012, the 3.3L header now has 2mm thick pipes and 3mm thick collectors of 321 stainless steel. Flanges are 12mm 304 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.
Great attention has been paid to building in maximum ground clearance and keeping room for the Syncro skid plate. The ground clearance can be appreciated in both the 2WD and the Syncro. Primary pipes are 1 5/8", secondarys are 1 3/4" and the output collector is suitable for a 2 or 2 1/4" exhaust system. Comes with right and left 02 sensor ports. Now with EGR port at the original SVX location.
Please order the FL3-225ss if you need a flange that matches the header.
