Cobb 2.5-Inch 2-Bolt Exhaust Gasket
The Cobb 2.5-inch 2-Bolt Exhaust Gasket is a replacement exhaust flange gasket for 2.5-inch 2-bolt exhaust connections. Used at the catalytic converter outlet, downpipe flange, or cat-back connection points where a 2-bolt flange with 2.5-inch bore is used. Replace at every exhaust removal and reinstallation — exhaust gaskets compress on installation and should not be reused.
