Review on Walker Exhaust 31377 Flange Gasket for Exhaust Pipes by Fuzzhead Nelson

08 combs. You need 2 for the flexible pipe that goes to the cats. They are pressed in when tightening the flange bolts. 40 lb ta and tighten clockwise like a car tire, but DO NOT skip over the bolts until the exhaust flanges are fully seated into the gasket expanders. You will also need one of the black triangular baskets that Revain recommends for connecting the coiled tubing flange to the center transducer. Much luck
