LML Duramax 4" FloPro H&S Tuner

Okay, guys, all you Duramax fans. Today is the day I got my 2013 GMC 2500 HD to not only up on the lift. We will be installing the HMS minimax tuner and then under the truck, we’re working on getting the factory exhaust off of it so that we can install this four-inch flow Pro exhaust. Now I opted to go with the muffler. I listened to a lot of videos with the straight pipe sounds badass, but I just want mine a little more toned down so right now we’re working on getting the old exhaust out just got these rusty bolts taken out of there, so we’re gon na start popping Hangers and see if we can get tailpipe out and then the fun part.

I believe we got a drop trans Mountain down a little bit, get the front half of this exhaust out, but a lot easier on the lift here. So I will come back once we got this exhaust out and we’re getting the new one in and then once we get our done and get it tuned. We’Ll do another video here with there see what she sounds like all right. Well, see you in a bit! Alright guys we’re back the exhaust is done and it went pretty.

Smooth lift makes things a whole lot easier, pretty sure if I was doing it laying on my back on the ground. It would never gotten done but start about 10 o’clock morning and I had a wrapped up by about two with the exhaust and there’s the H of this tuner. So I got that all installed. I’M gon na go ahead and fire this thing up and let you guys hear it, I’m pretty sure my gas mileage and my fuel mileage is gon na be horrible here for a while, because I took it out for a test drive and I can’t keep my Foot out of it sounds too damn good. So here you go I’ll, let you hear [ Music ] and there you have it that’s with the muffler on it.

So I’m pretty sure straight pipe it’d be just I’ve noxious League loud, but so far I love. It sounds great and when I’m cruising down the highway, you can’t really even tell it’s got an exhaust on it. It’S nice and quiet, but boy when you get on it, it’s there. You can hear it so hopefully over time here. If I keep my foot out of it, I can see if my fuel mileage and peruse and we’ll go from there all right, we’ll see you next time.
