Snoop's Take

The Walker Ultra EPA 16299 Direct Fit Catalytic Converter is designed specifically for Honda Accord models from 2003 to 2007, providing a reliable solution for reducing harmful emissions. This direct-fit catalytic converter boasts OE-style design features, ensuring an easy installation without the need for specialized tools, making it a popular choice among vehicle owners. Consumer feedback indicates that while the converter fits well and effectively prevents check engine lights, there are concerns regarding its legality in certain states like New York, with users noting, "The $290 Walker cat is illegal in NY. 😡" Overall, while it performs effectively for many, potential buyers should be aware of state regulations and compatibility with specific emissions standards before making a purchase.

Walker catalytic converter illegal in NY.
The $290 Walker cat is illegal in NY. 😡

Depends if your truck is ULEV II or LEV II emissions, if it is walker won’t work or any other aftermarket cats won’t work.
Quality and durability issues reported with some competitors
I just put an Eastern on. A lot of welding splatter and the angles were a bit off.
I did Eastern as well. Not bad but not great.

So I don’t know if I am expecting too much but buyer beware on this brand and aftermarket cat warranties in general probably.

the cat was mostly dust clogging up the screen.

Core Power Plays

The specs and strengths that make it shine.
Experience with catalytic converter lifespan
Had one in the past, worked fine for the four years I had the car, but was for a petrol engine.
Quality differences in catalytic converters.
Basically, from what I can tell, the car is great!
A misfire or oil burn will clog a cat up.
Discussion on the reputation of Walker compared to competitors
Walker seems to be best option now days.

Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’
Need for bolts and gaskets for installation
I need the bolts and gaskets for this part # 54782 and I couldn’t find any info on what bolts or gaskets are needed with this.
Go onto Walker exhaust website it’ll show you every piece in that system.
Reminder to provide vehicle details for installation help
This is just a reminder to review the [rules](https://www.reddit.com/r/MechanicAdvice/about/rules/).
Discussion on price differences between Walker and competitors.
I need to replace the catalytic converter on my 2000 SR5 4x4 (fed emissions).
Mention of alternatives to Walker catalytic converters.
Check napa, I work there. We have decent quality weld in cats at decent prices.
Need for additional parts for installation
Old bolts are very rusted and I'd like to replace the gaskets when putting in the new converter.
Using 2006 model which uses that cat then it's Walker exhaust bolt/spring set 35129 and pipe flange gaskets 31378 outlet and 31531 inlet.
Discussion on vehicle compatibility for installation
Thanks. I was having trouble navigating the Rock Auto site, but it all makes sense now.
Mention of EPA warranty requirements for aftermarket catalytic converters
Make sure you read and comply with all directions and submit the warrantee card.
Comment on the reliability of OEM parts compared to aftermarket options
OEM is the only way to go for a reliable and lasting fix when it comes to converters.
Need for vehicle specifics for accurate advice
both have direct fit replacements that are CARB approved, around the same price, and have a 5yr / 50k mile emissions and construction warranty.
Advice to consider OEM parts over aftermarket options
Honestly I would get an OEM cat.

Cautionary Callouts

Know the pitfalls before they catch you off guard.
Quality differences in catalytic converters
So in short, they might work, but you may have to put some time and energy into getting the results you want.
Cheap cats are just that cheap. Not fake but fit might be poor.
Will be replacing O2 sensors, and then the exhaust manifold/cats if the O2 sensors don't resolve the code.
Experience with catalytic converter lifespan.
Cheap replacement cats are 50$ shipped. You have a 50$ test pipe
Not sure of cause but am curious, do you regularly change your filters and have you have any issues with your O2 sensor?
Discussion on warranty claims and retailer involvement
Put in a warranty claim.
Discussion on the importance of addressing root problems causing converter failures
Misfires, air/fuel issues, internal coolant leaks, road impacts kill converters.
Discussion on the importance of fixing root causes of converter failure
Catalytic converters are very expensive.
Subarus don't typically play well with aftermarket cats
they ended up bricking my ecu, but after getting a new one installed they figured it out and i got away with no code, no new cat, and only down $330, but now i can use cruise again lol.
