Just Passed Pa. Emissions with Stainless Works Headers

I looked and I can't find my invoices for the parts but here are links to the 3" V-bands. (Race Parts Solutions had the best prices for the V-bands.)

As far as the ball clamps that attach the rear of the cat to the cat back flange, SW doesn't have a part number but Anthony Grosser will know what you want and they will make them up custom for you. You just want the end pieces in the illustration behind the off road pipes with the O2 bungs.

Let me know if I can help with anything else.

Do you have to use the factory cats for this, or would 49 state legal Magnaflow cats work?

i see no reason to use cats at all if you have a good tune on your jeep, it will pass any inspection emissions properly :-)

What about the rear O2 sensors reading catalytic inefficiency? We cant have the rear 02 sensors read "not-supported", or shut off in MA.

a "good" tuner can still fix that in the tune and not turn the sensors "off"

Ok...so who would a "good" tuner be? I haven't seen anyone else with LT post up saying they passed inspection with just a tune adjustment.

Johan and I tried every combination that he had on my Jeep with the off road mid pipe rear bungs plugged and it set codes every time. Your gunna see 0038/58 and 0138/58 either right at start up or after 5 to 50 miles. I had to buy rear O2 sensors for my off road pipes and connect them to run the tune with the rear O2's turned off. With the rear O2 sensors installed I now have about 600+ miles on my catless set up without setting any codes.

i know that no 2 jeeps are the same however my turbo setup with the rear 02's shut off and not plugged in do not throw a code, took 2 revisions from johan and theyre good to go for 7000kms with no lights
