great product, with all seals and new.

Great product, all the gaskets and new screws, washers etc were a plus. Some minor adjustments were needed to line up all the holes but worth the price.

Pros
  • Top
Cons
  • Long delivery time

Make sure you have all the parts

The only complaint about this product is that the screws provided do not fit this converter. I had to use the originals. And it didn't come with a gasket, so I had to use the original gasket. Aside from these issues, the converter worked as expected.

Pros
  • Free for educational purposes
Cons
  • There are new competitors

Glad it came with all the gaskets

Glad it came with all the gaskets, nuts and bolts needed for installation. The bolts on the mine are rusted to death and are 1mm smaller than their original size. It's great to get rid of that pesky check engine light and get checked again for emissions.

Pros
  • Slim design
Cons
  • Having issues

Fits but difficult to install due to dimensional accuracy

Fits but heat shield mounting point accuracy is poor and top heat shield mounting points are very poor. Can bend the shield to fit, but is annoying. The lower flange/spring bolts were not shoulder bolts like the OE bolts, so there was no way to ensure proper spring compression.

Pros
  • Easy to read control panel
Cons
  • Slightly torn

cheap clean cat! - Exhaust & Emissions

Available. To me it seemed to increase overall performance, probably because the last cat was so old and downtrodden. Fit was a bit of an issue, but nothing, a bit of fat and finesse didn't fix it. Since then it's been working great. the state test is passed and the test engine no longer starts. I recommend it.

Pros
  • New
Cons
  • All OK

It didn't fit and after 1 year the exhaust is leaking heavily

I bought it and it was actually installed by a Honda dealer. Unfortunately they didn't tell me that only the 2 main bolts, which are already the part of the engine where the catalytic converter is mounted, would be aligned. The 2 bottom bolts didn't match and the mechanic didn't even mention it to me. I discovered this about 2 months ago when I smelled exhaust fumes in the cockpit of the engine. I checked the exhaust leaks today and they are leaking everywhere. There were exhaust leaks on theโ€ฆ

Pros
  • Everything is fine!
Cons
  • Dear
