I have to agree, you should not have a code from the stright exhaust in a 7.3Have you pulled the code to see what it is?

no.. I dont have the exhaust on the truck I was reading in a diesel manual that they had backpressure vales and sensors ( I didnt know that) and was just wondering if anyone ever had a issue with it .. guess curiosity was just gettin the best of me.. thanks though I feel much better knowing I wont have a problem when I finally get the exhaust.. it is the next thing on the list .. im trying to do a mod every 2 or 3 weeks untill i have everything i want done.... for now

if your getting an EBP code...try removing the tube and cleaning it...they commonly get filled with soot and debris.....soak it in carb cleaner and problem solved

I think you are talking about EVBP valve (exhaust valve back pressure) it is a butterfly valve under your turbo and it has nothing to do with your selection of aftermarket exhaust, it is like a choke system before the aftermarket exhaust to help the engine warm up when cold. Two seperate systems.
