OBS Exhaust back pressure reroute kit

Marty's Diesel Verified independent store

→

This allows customers to cap off their factory Exhaust back pressure fitting in their manifold and run the sensor to the map line. Make sure you install this TEE before any boost f ooler you may have on the truck. This will make your Exhaust back pressure SEE a 1:1 ratio with your boost. Your PCM will be happy - but you can no longer use the EBP sensor to diagnose any back pressure concerns. A smoke tester or visual soot leakage should be used to identify exhaust leaks. Why should you use this? No more dirty/sooty exhaust back pressure tubes and sensors to deal with. Show more
