Perfect fit. I parked the car on a ramp and used a pipe cutter to cut off the old pipe. The new tube is inserted into the old tube before the catalytic converter. I used a 2 1/4" exhaust collar at the junction of the new and old pipe. I replaced the clamp holding the new pipe to the bottom of the engine with a new 2" exhaust clamp. The old one was too corroded to reuse This is the cutter I used: OEM 27045 exhaust cutter.
