back pressure issue

Ok im hearing that the 6.0L psd needs alittle back pressure to run rite and that you will see a check engine light if you try to run a 5" striaght pipe on a stock truck. Is it because of the vgt turbo, im not understanding why it needs the bp. Or is this just a bunch of bs and a five inch striaght will work just fine.

I set guys up with 4" straight pipe kits all day who have no trouble at all. I wouldn't worry too much about it.

so you think it would be ok to run 5" striaght. Have your customers said anything about power loss or running rough. Im just rying to do this up rite. I plan on doing a bunch of mods just not right away.

5 inch is overkill unless you want the deeper tone. Its also a bit tougher to install. 4 inch is all you really need.

I've heard no problems with rough running or sluggish performace using a straight pipe 4" full system. 5" systems can sometimes be a little loud if your running on the highway for long periods of time.
