My 2003 Yukon build

Sounds like a beast! I live that intake. Do you know what you're putting down to the wheels? Of course we'll need a video on your 1st test drive. What are you doing for exhaust?

Don't know the power at the wheels yet, that comes when we dyno tune it. The exhaust is Speed Engineering long tube headers and a Flowmaster muffler with a down turn exit

I have the 1 3/4 Speed Engineering with an MBRP muffler exiting at the stock location with the oem pipe.

Your truck sounds great.

I haven't decided yet whether or not I am going to change my exhaust setup or not. I decide that once I drive it for a while and how I like or dislike the sound, especially inside the truck

Makes sense. I have alot of drone with mine, which is annoying.

Be sure to post your dyno report after the tune. What MAF is that?

There will be a dyno video and graph. The MAF is stock, or are you talking about the throttle body?

Just a small update. I changed the exhaust tubing and muffler setup. At first I ran it like I had it before the build, with the Flowmaster muffler and 3" downturn after the muffler. But Honestly that was to loud for a daily driver. The headers and no cats really made that thing loud. Now I run 3" stainless tubing all the way, with a 12" Vibrant resonator/muffler after the merge pipe, then a bigger Vibrant muffler ( you can see through it) and another 12" long Vibrant resonator just before the exit . There is a V band connection right where the axle is, so you can't see it in the picture. Much better now, still loud and screams when you step on it but much quieter at idle and cruising. Almost done with putting the 500 miles on it , then oil change and the dyno tune

That intake is sweet! Engine sounds great! Nice work!

Brake upgrade. Wilwood 16" big brake kit with 6 piston calipers. I also got the parts for the hydro boost conversion. Installing the brakes is pretty straight forward. They tell you to put Loctite 271 on the bolts, which would have been nice to include in the kit, since it's something needed. No big deal, I got a bottle at the auto parts store. You will need a torque wrench and 40 Torx bit. Everything else is just regular wrenches and sockets



The difference in size to the stock rotors is staggering











Only parts missing right now are the brake lines and the brake fluid, then I can finish the brakes up.

Nice. I put the Wilwoods on both my trucks. Awesome brakes.
