exhaust backpressure

[Cj Ford]

will doing a 4" turbo back straight piped make the back pressure sensor or back pressure valve cause a trouble code or check engine light to come on.. not quite sure how either of those work and what they do.. i was just doin some reading I didnt even know they had those

no it shouldnt show any trouble codes it will be fine ive never heard of anyone having codes thrown from the the obs 7.3 nbs 7.3 or the 6.0 litres none btw it sounds so much better ith an exhaust!

on a 7.3 it wont cause any problems....

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?

[Cj Ford]

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.
