Yukon Dual Exhaust

[CJ Rodarme]

I plan on doing away with the spare so that wont be an issue. And I don't quite remember why the chicken was on my head in the pic but I figured it would make a funny picture and I've been using it for profile pics ever since lol

this is just thier standard image but this is basically what heartthrob sells for your truck. it says 2002-2006 avalanche and 2001-2006 suburban yukon 4.8 and 5.3. they dont offer a ss kit so i would coat the exhaust in some diy vht exhaust spray. p/n 1008060

limited shopping selection since they are kind of on the fringes of the exhaust world. autoaccessoriesgarage.com shows it listed for 406 free shipping but ive never used them. maybe contact heartthrob directly?

Cool. Looks like the same setup as the one I was looking at. There’s also options for a flowmaster 10 or 44. Any preference between the 10, 44, glass pack (the one I originally linked) or otherwise?

Looks like it goes from a single to a dual. Not what I consider a “true dual”. All the 4.8/ 5.3 factory setups that Ive seen use a y-pipe thus my recommendation to use a setup for a 6.0 which doesn’t use one. Unless you’re willing to settle for a dual from there back only. But the 6.0 midpipes wont bolt to the 6.0 manifolds I don’t believe so 6.0 headers would work. I don’t see the point going from 2 to 1 back to 2.

Yes the Denali exhaust is true dual all the way to the muffler so my recommendation is to buy American Racing or Kooks headers which replicate that and fit exact. Then you just need to have a muffler shop run 2 pipes from there back, incorporating 2 separate mufflers. That way with the headers you’re all the way back to just in front of the rear tires plus they sound badass. I don't have pics of the stock exhaust but here's my AR headers. They fit perfectly on my 02 Denali. I have a dual-in single-out Aero Turbo muffler with a single pipe for the last few feet where it goes up over the axle but like I said you could run 2 pipes and 2 mufflers. The biggest problem is those last few feet unless you do away with the spare but if you're running huge tires like you want, a regular size spare prolly isn't any good to you anyway. BTW why is there a chicken on your head in your avatar pic?View attachment 215485

Are those catted pipes?

Yes mine have high flow cats.

Nice I'm gonna have to look into those. Are they considered y pipes even if they are a dual to the muffler or would that be mid pipes?

Just mid pipes. There’s no y pipes on the 6.0.
