Outstanding Catalytic Converter Replacement

After trying this product, my automotive system has never been better. The efficiency it brings to my emissions system is top-notch. The ATP Automotive Graywerks 101304 Catalytic Converter Replacement has given me an excellent driving experience. It was a seamless fit and provided noticeable engine improvement. The only con I would mention is that the installation process can be time-consuming. But overall, a great buy for anyone looking for a reliable replacement.

Pros
  • Effective at reducing harmful emissions from vehicles.
Cons
  • Minor Issues

Some of the supplied screws do not fit and .

Some of the bolts supplied do not fit and the heat shield had to be bent and a bit of work drilled but with it fits a little fiddling and the check engine light is still off.

Pros
  • Designed as a direct replacement for the original equipment ensuring the header lines up and flows like the original block
Cons
  • Could have chosen a newer model

Good Exhaust Manifold

This was one of the cheapest manifolds I could find including the catalytic converter. It fit my 2002 Honda Civic exactly as it should and I even used old O2 sensors from an old manifold. It's made in the Chicago area, although some parts ship from China (surprise!). The only issue I had was that the springs used to attach the bottom of the catalytic converter to the exhaust system were so stiff that I had to wire them to get the bolts to fit. I would recommend using old nibs if possible.

Pros
  • Developed from OEM ECU monitors, repairs catalytic converter, checks engine light and restores correct emission levels
Cons
  • Too long to wait
