Exhaust for 6.4

[cooper09250]

I am going to order the Spartan and dpf/cat delete kit for my truck. I want to buy the sensors that go into the pipe, instead of trying to take them out and strip them out, OEM only, and does anybody have the part numbers on those? I also want your opinions on what exhaust you recommend...I don't want anything that will be loud, and are the gains for bigger exhaust significant, because the stock pipe is already 3.5". Thanks for the input!

I'd advise going with Powerstroker67's delete pipe from Rudy's. Here's my delete thread:

The part number for the sensors is 8C3Z-12B591-D.

Enjoy!

Spartan carries the sensors and believe they are cheaper then the dealer.

I wasn't aware that Spartan carries them, but if they do, for comparison purposes, the dealers charge $75-80 each. You would probably be fine just buying two. The one furthest upstream comes out pretty easily, especially if you PB blast it for a few days before doing the job. The middle one's not much harder.

The back one is a *****!

[mdavis203]

Yes it is. I put a wrench on it, gave it a tug, then left it right where it was. Even if I could have gotten it out, it would have been so scarred up that it would have flagged the dealer that I had been changing it out.

Thanks for the input on the sensors...what do you guys think about cat back exhuast?

Do downpipe back exhaust. If you leave the DOC on the truck, it could potentially clog overtime.....and there will be barely any exhaust note change.
