straight pipe exhaust question
Hey guys I have a few questions about putting an exhaust on my truck my smog is up next mo. So im gonna do it after that but i wanna get all my ducks in a row before I do so.
First question: which straight pipe is preferred and does size matter
Second question: this one could potentially get me shot but I didnt notice an O2 sensor but if it does have one that i just didnt notice how would you go about not thowing a code for emmisions? If it doesnt have one then this question doesnt apply
Being as its gonna be a straight pipe does the brand really matter as long as its manderal bent and when i ask if size matters i mean 4" vs 5" turbo back
Thanks guys

The 6.0L doesn't have O2 sensors. You don't even need to have a brand name, my local shop bent my 4" for me, I bought a 4" downpipe and they bent the rest. As far as 4" or 5", that depends on what your plans are, 4" is fine for stock trim-slight mods, you start getting into serious mods and you'll need the extra flow of a 5". Same goes for where it exits, stacks/under the cab/in front of the tire/behind the tire, that is all personal preference.

Check clearences when bolting it up. I thought I had enough on my cross member once, the rattle was ANNOYING. Regardless of what you buy, get a turbo back and ditch the 3" down pipe. I am plenty happy with 3.5 DP/4" straight pipe.
It's going to scream when you ditch the cat/resonator! While most will like it, there will always be the hater asking why you did that. Also be prepared for "What kind of turbo is that?" Most people don't believe an OEM turbo can scream like that and it has to be an aftermarket turbo.

Considering you just did a hpop swap, switching from cool guy straight pipe to el lameo cat exhaust would be a walk in the park. If you can support the trans, it LOOKS like the down tube would fall right out without the cross member in place. At least that's what I iwas thinking when I was wanting the down tubeout of the way for my EGR cooler delete job.
