5.3 Style Y-Pipe on a 6.0?

[Tonyrodz]

I have two brand new high flow cats I'm selling.

Don’t go to a 5.3 exhaust, the 6.0 exhaust flows way better.

Dan, how much different is your exhaust compared with the pickups? It is possible that up to the muffler they are the same.

My Denali 6.0 is completely different than the 5.3 systems- it's dual all the way back to the muffler and bigger diameter piping. No y-pipe. When I installed longtubes the entire system is included all the way to the stock dual muffler input and it's completely different than the ones sold for the 5.3/ 4.8's.

No, I mean same motor, different chassis Mark.

This is similar to what I have except it has 4 cats (California Truck). My truck is a 2500 Yukon XL, and I havent found that the exhaust parts interchange, but I could be wrong.

2500's are different than the 1500's, parts don't interchange.

ok yes 2500 makes a big difference. magnaflow has a listing for California legal catalytic converters for your truck. on my phone so the images dont come up right but it shows a left and right side. then it also lists a universal one probably for that last one infront of the muffler.
