Zane Merva Executive Editor, GM-Trucks.com 7/31/18 We've certainly seen a lot of photos of the all new 2019 Silverado and Sierra. Photos of the interior and photos of the trim packages. Photos on-road and photos off-road. But what we have not seen yet is how the 2019 Silverado and Sierra's new T1XX platform looks mechanically under the surface. Until today. GM-Trucks.com has obtained exclusive copies of parts diagrams for the next generation Silverado. From these drawings we can gleam just a little bit more about how the next generation trucks are different from their predecessors. Set One: Front Suspension, Differential, Axle, and Driveshaft Our first batch of drawings show us a few things, mainly the new T1XX front suspension setup (which is similar to the Colorado), a new HD-like front differential, a new rear axle with new yoke, and a new driveshaft setup. Set Two: Front and Rear Brake Calipers Our second batch of drawings show the new 2019 T1XX front and rear calipers (with electronic parking brake). Set Three: Engine Blow Out, Dual Exhaust, Cold Air Factory Intake And our third batch of drawings show what the new L87/L84 looks like blown apart (with individual cylinder deactivation instead of an AFM VLOM). We also see the new dual exhaust and brand new airbox design that draws cool air from the front of the vehicle instead of the side fender. Thanks to our "GM deepthroat" for sending these files our way. Next week we head to Wyoming for our first drive of the 2019 Silverado while our 2019 Silverado LTZ is being shipped to our dealership from the factory.
The story goes back about two months I was driving and thanks to a guy in a Mercedes I had to slam my brakes really hard and go from 45 MPH to a dead stop in the shortest distance I've ever seen a full size truck stop. My brakes did exactly what they're supposed to do and I was really impressed because my truck stopped 6 feet before destroying the foreign SUV. However since that happened I now get a message on my odometer that says "SERVICE BRAKE SYSTEM". Logically it would be the brakes but I know my brakes are fine because they don't squeel or vibrate when I stop or anything unusual. I get the message when I'm accelerating or suddenly take my foot off the gas pedal. When the problem started it wasn't that bad but now it's getting really bad. Here is a youtube video of my driving to work yesterday morning taking my foot off the acceleator. It's starting to bother me because I live 45 miles from where I work and having that dinging going off when I'm driving to and from work is very annoying. I already threatened to trade my truck in to go back to a Ford because sometimes that works lol. All kidding aside though, any and all input is greatly appreciated. Thanks you guys in advanced!

I have a 98 GMC z71 with a 5.7l 350 vortec that is way too quiet. I plan on removing my cat and putting a different muffler on it for a better sound. Could that in any way affect my engine or mess up anything?
