back pressure issue

[shaggy337]

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 have heard two sides some say yes some say no. I don't know to be honest with you.

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 like that deeper tone. One of my buddies has it on his 6.0L. sounds good, im just trying to see if its going to hurt anything on my stocker.

That was actually shaggy337 using my log in (we use the same computer here at work). I'll post up some pics of my Dodge in the next week or so.

where do you guys work. I'm originaly from morgan hill. Good to see some people from the bay on here. Maybe you've seen my rig around town. Straight piping your truck is perfectly find and will not affect anything.

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.
