Review on 🚗 Walker Ultra EPA 16386 Direct Fit Catalytic Converter for Enhanced Exhaust Performance by John Raj

My Park Avenue hasn't used electricity for several years. And we had to stop driving it over 6 months ago because the performance was so poor we could only go about 45mph. I replaced the engine parts that may have caused this and took it to the mechanic when the car was still not running well. For some reason the mechanic couldn't figure it out. I then pulled the 02 sensor and the car ran much better as the exhaust was escaping through the exhaust manifold. I just installed it and the machine runs better than it has in years. I'm slow so it took me about 2.5 hours. You cut off the heads of 4 screws on the exhaust manifold, cut off the pipe and screw on a new one. I also needed: 4 x 3/8-16x1-1/4" bolts (I used stainless steel); Walker Gasket 31587, and I highly recommend getting a Vibrant 1171 exhaust pipe clamp. It's more expensive than other clamps, but seals much better and is very strong once installed I couldn't be happier.
