I'm going to swap out my exhaust system from the cat on back tomorrow - I'm going with a Dynomax high flow cat that has dual 2" inlets and a 3" outlet, then into a 3" straight pipe, then into a large Dynomax UltraFlo 3" muffler, then a 3" tailpipe. I have not replaced the 2 oxygen sensors on this truck before and plan to replace them as part of the new exhaust system. What is the best brand oxygen sensor to use on this engine/truck combo?

 

Ngk..

 

Thanks! Is NTK also made by NGK?

 

Yep, same company.

 

Thanks! That's what it seemed, but just wanted to double-check to be sure.

 

NTK part #23151 and 23014 are what you want. I have the same truck as you.

 

Thanks. Purchased them today as part of the exhaust system replacement. The new 3" cat-back exhaust system sounds nice and the truck seems to have picked up a bit in performance.
