Aftermarket exhaust question..

[TNpowerstroke]

Hey y'all I just bought an 03' 6.0 king ranch. I have a few questions...Will putting an aftermarket exhaust on this truck mess up anything with the motor? I have heard some of the horror stories about this motor and do not want to do anything that will put this truck in the shop. It has the EGR delete done and is bone stock...Would greatly appreciate any help because i really want this truck to roar.

No, adding aftermarket exhaust or deleting the cat and/or muffler will not bother the motor at all!!!

Ok that's good news. I guess the thing I was worried about was back pressure with the turbo and everything. What's the difference in a turbo-back exhaust and deleting the cat and muffler? Could I get the sound I want with leaving the cat on and just deleting the muffler? I live in TN so there ain't many restrictions but really didn't want to remove the cat.

I would get rid of the cat, and leave the muffler....or get a straight through muffler....

If you have a 2003 you want to go complete straight pipe! You have that awsome turbo like me and you will love hearing that thing trust me! It never gets old!

Yea man i love that turbo sound!! So with a complete straight pipe you wouldn't have to worry with the back pressure and all that stuff with the turbo or is that just complete BS to begin with? AND what does the cat actually do with a diesel?

u dont have to worry about back pressure, less is better....
