This 2.25" mandrel bent assembly consists of a flanged Y-pipe that connects to the factory cast iron manifolds, then to the back of the catalytic converter (offered separately as P/N 2010036). All necessary flanges, gaskets and hardware are included for a great fitting, bolt-on installation. Constructed in durable 409S stainless steel, the system is covered by Flowmaster's Lifetime Limited Warranty. (Fits 75-76 Models without Smog/Air pump)
