Just won a set of 8.1L headers
 

Supposed to be The Other Guys headers for my Yukon XL with the 8.1L. It looks like they're probably a short to mid-length header. Less than $250 delivered, we'll see what happens.
I had been wanting the Stainless Works pieces but found these on Ebay so we'll see how they work. I think I've got the exhaust leak that a lot of others here have mentioned. Maybe this will motivate me to finally rig up my remote oil filter setup too.
Thanks,
Michael

Do a dyno tune after puting these on, will make all the difference.

Yeah, I think I've got EGR so I'll probably send out the ECU so I don't have to hook that up. I should run it on the dyno before and after just to see what it says.
Thanks,

You need to replace the factory muffler to. That is a real choke point on those 8.1's
