Great Buy!

Perfect fit for my 1998 Chevy Blazer.
Hopefully will never need again.
Verified Buyer - Submitted 7 years ago
Replace due to check engine light being on. Didn't solve problem but something new never hurt the performance of a Chevy especially with high mileage.
Perfect fit and great quality

This was an easy install once the old was removed, new cat fit perfectly and went thru emmisions with a passing grade first time, would recomend this unit to anyone needing a replacement. I consider myself just a backyard mechanic with limited tools and got her in with no problems not to mention the savings!
Bottom Line Yes, I would recommend to a friend

Can I put this on my 02 Chevy s10 4.3
Verified Reply - Solomo
Hi Jay, I'm glad to help you! This Walker EPA Ultra Direct Fit Converter (Part # 15827) does not fit your 2002 Chevrolet S10 4.3L 262CI V6 engine. We do have an exact fit part available online for your vehicle and the part number is 93226. Please enter your vehicle on our website and search for this part to check the fitment.
Will the gaskets come with, or do I need to buy them separately
Verified Reply - Solomon
No, Scott! This Walker Converter - Part No. 15827 does not come with the gaskets, you should purchase them separately. You will need the Walker Exhaust Flange Gaskets Part No. 31571 and 31589 for this converter.
where is the O2 sensor, S1 B1 located?
Open Reply - Mike the Auto Parts Master
For further assistance, please provide the year, make, model and engine size of your vehicle.
Do you need special tool for co2 sensor....
Open Reply - Ron the Auto Parts Rebel
Not necessarily a simple wrench can be used to remove an O2 sensor however there is a socket specifically for O2 sensors.
Will the check engine light come on when I take out the 02 sensor ?
Open Reply - Kevin
Yes it will come on if you take out the O2 sensor.
