it looks like a dirrect bolt on replacement, im just wondering if im gunna have any issues with 02 sensors or the egr, ect.

 

u shouldnt have any problems with your 02's

 

Well those aren't cats on it, those are resonators. Swap them out with cats, it will work right, and ofcoarse getting an updated custom tune for them.

 

I have them, they work well. You will throw the p0420 code (cat inefficient or whatever) but I developed a mod that you could use if you wanted to stay cat less. Search Gotts O2 mod. You will need O2 extensions and probably some better gaskets to connect to the head, I went with SCE copper gaskets. You may also want to run Stage 8 locking header bolts which also work great because the studs on these trucks are not that good.

 

they have the egr hookup

 

I'm running them too, I saw MPG improvements and they went on great. I replaced the resonators with Maggie highflow's. Runs great and passes emissions!
