ok guys i have a customer that wants straight pipe. seems he has to compete with this 5.9l brothers. so what can i do?

 

I wouldnt mess with until you know exactly what you are doing as this is not like straightpiping a regular common rail (but you probably already know that).

Have a look at this:

im kinda confused at what you are saying?

 

Do you have a fooler box to bypass the emmissions/EGR stuff?


Did you read the threads I gave links to?

 

DE, Obviously not. A 6.7L truck will without a computer by-pass go into full limp mode, mileage and power will be dramatically impacted. The truck will not rev above 2000 RPM (or is it 2100) and you will not enjoy the $60k paperweight you just created.

My advice, do not mess with these emission controls.

 

Nothing legally. Doing things like that can end up getting your business license revoked and very big fines handed out if the wrong people hear about it.

 

I know this is an old post, but you can easily mess with the emission controls now

In fact, you can turn them off entirely with some some programmers.

 

Sensor sims do a pretty good job of keeping the ECM happy when the BlueTec components are deleted and aftermarket software (such as Smarty) isn't present.

I don't recommend straight-piping... our 6.7L exhaust uses a resonated AeroTurbine & 409SS tubing with O2 bungs (not required on C&C).
