We installed long tube headers but now need to add catalytic converters in order to pass MO state inspection.  Would it work to add the one on each side like how the factory does?   Will they get hot enough for the O2 sensor if added behind headers?Tony B.Jul 16, 2023
Best Answer:Hi Tony, thank you for reaching out. We are unable to answer your question accurately due to a lack of information. Kindly call our parts team at 1-866-529-0412 and tell us more about your vehicle. Have a nice day.

Is this for Bank 2 or bank1?Albert M.May 19, 2022
Best Answer:Hi Albert, I'm glad to assist you. This is for the rear location, underneath the chassis, not on the engine bay location. This is a universal type as well, not a direct-fit part. For us to carefully check and be accurate on the part that you need, please provide the complete information of your vehicle (year, make, model, submodel, and engine size). The 17-character VIN would also be very helpful. I hope this helps. Happy shopping.
