1990 Jeep 4.0L I need to install new cat, muffler, and exhaust pipe. I am planning on getting a direct fit cat. The direct fit cat I am looking at has a outlet diameter 2 1/4. Inlet side, and outlet side of muffler 2 1/2. Exhaust pipe 2 1/4 inlet, and outlet. So basically a whole new rear exhaust. Anyway will a 2 1/4 pipe fit into a 2 1/2 pipe? I want to use exhaust clamps, so there is no welding required. Will this work?
