With tax season approaching, I am playing around with the idea of an exhaust upgrade on my 2004 GMC Yukon XL with the 5.3L.
I had a set of 40 series flowmasters on an old Scottsdale I had and I absolutely LOVED that sound. And if I ever buy another old 80's Chevy/GMC truck to play with, I am going that route again.
I do like the aggessive sound, but this is a family vehicle. Hauls 3 boys, the girlfriend, and my butt. Mainly highway trips. So cabin noise is a definite issue for me. But I still want a mean sound.
I had a 93 K3500 Dually with the 454 under the hood and that had a Magnaflow muffler. What series, I have no idea. It was on the truck when I got it. That was nice. Decent rumble, but not annoying when under power or on the highway.
For the Yukon though, I think I would like to stick with Flowmaster. (Unless someone else talks me out of it.) I have it narrowed down to either the 17341 Force II or the 17342 American Thunder.
I know that the 17342 will be louder, but is it going to be annoying at highway speeds in the cabin? If it is, then I will go with the 17341. I like the 17342 dual exit though. From the instructions, it looks like this exits right out the back? Not sure that I like that too much. I like the side exits personally on a truck. But I can always have this modified if I want. I have a local shop that has done some custom stuff for me and they would be more then happy to modify the 17342 to exit out the sides if it doesn't already.
So what have others gone with? I am looking at just CAT back for now. Maybe some day down the road I will upgrade headers and such, but for now, just CAT back. Maybe I am just missing the growl? Right now I like the grumble the stock has at an idle, but I want more. Just not quite like my 69 Cutlass. Headers, 3" in and out glasspacks, neck down to 2.5" to get over the rear axle, and dump right out behind the rear bumper. HOLY COW does that dog have a bark! I just want a gentle, but firm growl out of my Yukon.
