Just got my MRT Extreme kit installed and damn does it sound more aggressive now! The good part is when you are just cruising it is pretty quiet, very close to stock. When you smash the throttle, it comes to life with a vengeance. I will add some videos shortly of the idle and idle with pedal to the floor. It still has the dramatic pop over 4k rpm, but much louder and aggressive in nature. The inside of the truck still catches the rumble during heavy acceleration and can't be happier with the outcome. MRT killed it with the kit! Just an FYI, you will need to cut the driver side stock exhaust pipe near the top bend over the axle. The pipe is angled which makes the cut a little harder to keep straight. The new system was a struggle with two people to get the rear tips aligned properly, but three people did the trick.
