Hey all, I was going to pull the manifolds to replace a couple broken manifold bolts. I want to install long tubes while I have it all torn down.

The only issue I'm having is with the mid pipe. The factory does not have a Y, and stays as duals all the way through the factory muffler. Does anyone make a bolt on midpipe setups? I was going to go with Pacesetters, but am open to other options. All I've seen is LT's with a Y pipe setup.

Also, 1 3/4" or 1 7/8"? I'll likely stop at intake exhaust and tune.

You have to look at the options for a 6.0

The 4.8 / 5.3's have a actual Y pipe where as the 6.0 has two separate pipes.

Yeah, I'm just having issues finding any part numbers for the 6.0 setups.

What long tubes are you looking at?

I'd like to run the Pacesetters, or maybe the Dynatech. Stock catback for now.

Well pacesetter doesn't make a ORY for your application but Dynatech, Stainless Works, American Racing, plus more all do.

Thats the problem though, I can't run a Y with the factory cat back. Nobody sells the Denali intermediate pipes, at least they don't anymore.

I might just get a 3" single pipe catback for a regular Yukon, and run a Pacesetter with Y pipe setup.

With the exception of pacesetter the others make intermediate pipes for you app. Look for Silverado ss also as their exhaust is the same as Denalis. I've been down this road.

Its a low demand product on an 11 year old vehicle, maybe they stopped making them?

Kooks makes a matching intermediate pipe with cats, but its priced at $600. Yikes!

The ARH part number for headers and catless pipes is GMT6E78NC, going for about $1400
