Any help will be much appreciated.

I don't think the SRT mid pipe cats will work. There is not enough clearance between the trans pan and cat. I just kept the OBX mid pipe. Why are you getting the srt mid pipes when the headers come with their own set of catless ones?

The OBX headers don't have a cat, just a resonator. I want to keep my jeep emissions compliable since I'm military and don't know where ill be going next. Plus I don't want any codes for O2 reading out of limits.

Meh.. unless your coming to the hippie state of California then you'll be fine. If you are coming to cali then just keep your out of state plates on since your totally within your rights too. Use the obx pipes and just splice the cats in. You'll still get codes due to the flow rate being messed up i think but wont get the smell of fuel haha.

Re: OBX Long Tube header 2007 5.7 Install

So do you currently have codes for the O2's Sleeps? If not, was it taken care by a tuner?

A custom tune form someone can turn off the back 02s off so the codes won't show. Which is what im doing and getting a proper tune at the same time.

Re: OBX Long Tube header 2007 5.7 Install

Are you going to be custom mapping the fuel trim/parameters? Won't turning the cats off mess with the fuel trim/parameters?

The front ones control all that. Back ones are used for something else. Forgot what though.

Re: OBX Long Tube header 2007 5.7 Install

I thought the fronts were more for reading temp and flow, the rears after the cats read the air mixture to determine emissions. I'm no expert on this.

The back ones are only used to make sure it is emissions compatible. Mine are turned off thru a custom tune.
