Solid and well built

This is a very solid setup and the construction is very good. I had one small hiccup with the muffler the diameter of the outlet was a bit small as to not let the exit pipe side to slide in to the muffler. I used a 5 lbs hammer to gauge it out just a little bit and Boom done. This kit fits up perfectly to the stock mounting brackets and looked amazing! But my only problem with the whole thing was the sound this kit produces. Coming from a diesel 4 didn't sound bad at the time, I know I have a tiny 3.5 ecoboost, but the 4 exhaust to me made it sound like a Honda. I have to say I wasn't a fan. I did drive it around for a few days hoping it would change tone a little bit. So I have taken it off and put the factory back on or at least till I find a resonator or different muffler. But as far as quality goes like I said solid and very well built kit from MBRP. I would buy another setup from MBRP just not a big 4

OMG this is friggin loud as hell

This was only a slight challenge to install in my driveway. Rolled the truck up on the ramps and in about two hours I was all done. It's a little difficult to route the rear pipe over the axle, but getting the old pipe out is more of a challenge than installing any part of the new system.. I'm no mechanic and I did it alone in about two hours so there. Romp on the gas pulling away from a stop and let it rev!!! The deep magic rumble of the internal combustion engine turns into that awesome howeling roar we all love. Wow. But this thing is just so friggin loud it's ridiculous. I often put the shifter into manual and up shift early just to quiet the motor, as well as driving a tad slower, which I oughtta do anyway. And there is no escaping the sound coming in through the floor. It sounds really deep and badass but when your droning down the hi way it gets annoying. I'm certain my neighbors don't like it when I pull out at 545 and wake them all up. But really who gives as shit about that.
