Description:You must remember to re- torque the bolts after a few days to allow the gasket to take a set. The new Stillen header has no gasket here so the problem is cured. The have been a few new companies to come out with an SR20 header recently: Pacesetter This header looks like a cheap rip off of the old style Hotshot. It also ripped off the experimental secondary crossover pipe that was featured in one of my SCC articles. Too bad they did not read the article to find out that it did not work. It has thin tubing and is painted with a cheap black paint that instantly burns off and wreaks havoc with your 02 sensor. The flex pipe is of low quality and will not last long.
