Short video of my 2011 Yukon XL 2" spacer lift 33's, Fab four bumpers, winch, DNA long tube headers, delta flowmaster with stock resonator. I had a cherry bomb extreme clamped to the header collector but it was way too loud for my daily driver.

Sounds good.
Tight, had to dent a section with a punch because the steering column touches

Have any pics of the mods needed?
Just a hammer and a brass punch, i also made my own o2 sensor restrictors with 3/8" copper tubing
pretty much the same, did yours come with a cross over or did you want true duals?

What's the purpose for those on the O2's?

I bought the crossover.

It should keep him from having to program the rear O2 sensors to be ignored... it will make the reading from the rear O2 sensors appear to have a catalytic converter even though there is none.
Lots of guys use these instead...
Ya i was going to buy those but I was impatient and didn't want to waste time or money i had tubing lying around so i figured what the heck if it dont work then i'll buy the non foulers. So far it's been 6 days and no CEL. I guess its working.

I put the same ones on my 11 Yukon XL 2WD, everything was perfect other than the o2 sensors on the old set up. One was stripped so I had to get another. No mods needed. But I went in with my hp tuner and turned everything I took off, off. I just need to get the money so I can dial my fuel in now. Sounds good!!
