I have a '07 Yukon XL Denali that is starting to show signs that the exhaust needs to be replaced after 17 years.

I would like to replace it with the exact same stainless system since it has lasted this long. The crossover pipe with the CATS I am not sure about but probable they need to be replaced as well.

Wondering if any one might have a system off a 2013-2015 Yukon XL (or maybe Suburban/Caddy) that would fit mine? If so let me know.

I have an '07 also with 243K on the original exhaust, but the exhaust is still perfect. Where is yours failing, exactly?

To answer your question though, I would check car-part.com for lower-mileage units in your area or in a drier climate. I would focus the search on '07-'13 rigs but I'm not 100% certain that the system is the same across that year range either.

I found the tailpipe coming out of the muffler was rusted and falling off this morning. I was able to tie wrap it up for now.

I am going to have a local guy I trust with my Yukon to put it up on a lift to see how bad (or good) the rest of the exhaust system is. Might be all good for I know......LOLLLL

I found a local guy selling parts off a 2015 Yukon (not XL) and I wonder if the exhaust on that would work?

Not likely to work :-(

You might take it to a Midas or Meineke and see what they say. The system is stainless steel, so the damage may be limited to that one area. In which case, a muffler shop can make short work of the repair.

Thanks for the info.

I am taking it to my local guy tomorrow so I will find out more at that time.

I also checked Car-Part.com and nothing local.

Mine is even still pretty much rust free. However when changed the oil last weekend I saw the braided sleeve thingy that is right behind the cat coupling fell off and slid back the pipe against the muffler. So it's just hanging out there now.

I suggest taking it to a local exhaust/muffler shop. As @Geotrash stated above, it may be just a selective patch job, repairing any sections that are failing or about to fail.

Careful when shopping, most exhaust systems for these trucks use 3 inch tubing while our factory exhaust uses 3.5" tubing.

Your Y-Pipe with cats is a narrower diameter but does not have a third cat. It also connects to the rest of the exhaust with bolts/studs and nuts. The later setup (forget the year) uses 3.5" Y-Pipe with three cats and a clamp to connect to the rest of the exhaust.

If you are in California or a state with California or New York emissions, you have to replace it with those types if you live there.

My truck came with California emissions as it was ordered for a dealer in Pennsylvania. It now sports Federal emissions cats and lives in Florida.

Everything I’ve seen on Denali Gen 3 & Gen 4 (07-14) is that they have a full stainless exhaust, less the manifolds.
