Rockauto has a Walker Y-pipe assembly that's 49 state legal for $430, and some slightly cheaper 48 state legal one's ($300 range). I used the walker 49 state one on my Blue '04 before I got rid of it. Fit was was good and overall construction was decent. The only issue was passenger side cat heat-shield was very close to the front shaft on the truck that had a 2" TF lift. The front shaft balance weight would hit the heat-shield if the the wheel was turned a lot at a dead stop and then you took off. There was enough suspension bind that it would just nick it. BUT the truck did not have a adjustable panhard bar so the axle was not perfectly centered. It really was nothing a slight tap of a hammer would take care of. It happened so infrequently I never did anything with it. I never clock the wheel before accelerating from a stop - it really only happened to my fiance'.

Hey Mike, I've been getting a CEL and "Catalytic efficiency below threshold bank 2" message for well over a year. I managed to sneak it through my last state inspection after I reset the code and drove it long enough for everything to be ready. Also occasionally get a message regarding one of my O2 sensors. Going out to check current codes.
OK, todays codes are:
PO134-O2S CKT NO ACTIVITY DETECTED 1/1
PO430-CATALYTIC EFFICIENCY BELOW THRESHOLD BANK 2
P1450-MANUFACTURER SPECIFIC DTC
PO133-O2S SLOW RESPONSED 1/1
The PO430 has come back every time after probably a dozen resets over the last year and a half. Sometimes takes a few hundred miles for it to come back on. All the other codes are recent,....in the last two months

I considered having the Odo reset with the Test Book procedure, but,....why bother. I plan on keeping this truck indefinitely.
I replaced both the front O2 sensors with correct Bosch sensors 2 years ago. Curiously the new driver's side O2 sensor did not work,....so I put the old one back in and I had no codes for about a year of driving with a daily commute of about 60 miles.

I am constantly impressed by the OP's and their restraint after you hit post reply with a condescending/snide/rude/ assholey responses.

Frank,
Do you even know the reasons for a good forum, it is to learn and for you to say that my reply was BS is not right.
You have to admit that driving for a year plus on a flashing CEL is stupid and now he has to pay the a lot more in repair then if he just took care of the original issue when warned by the CEL.
