Justin: Hey, everybody, Justin with americanmuscle.com here, and welcome to another episode of "Builds," the place where we highlight and feature some really cool customer and employee rides, do some wrenching and show you guys the results. Now, here with me today in the studio is AM customer and friend Mike and his beautiful 2015 GT. Just picked this thing up, man, and it really is sharp. Tell us the story a little bit, though, because this isn't your first Mustang. Right?
Mike: It's my second.
Justin: Okay.
Mike: It's my second, but it is my favorite. About 18 years ago, I had a 25th anniversary that I picked up, drove it about a year, year and a half. And it got to the point where I was just starting my career, and I had to get to work. The Northeast winters aren't favorable for Mustangs all year round all the time. So I had to sell it, get the 4-wheel drive to get back and forth to work, and here we are, probably for the last 16 years, I've been wanting one. And about a year ago I finally got the green light from my wife. The time was right, and I was looking and looking. And then I was about ready to get the 2014, and when I saw the 2015 unveiled, I was just like, "Yeah, that's it." That was the winner.
Justin: How you liking the car so far?
Mike: I love it. It's beautiful.
Justin: But it needs more power, right?
Mike: It needs a little more power.
Justin: Well, that's why we're here today, of course. Mike just brought his car in. He's not going crazy right away. We're gonna start small. We're gonna take care of some of the Mustang basics, give the car a little bit more power, a little bit more sound, and maybe make it a little bit more fun to drive for ya...
Mike: I'm ready.
Justin: ...and have some fun. So I tell you what, Mike's gonna get out of here. We're gonna get to work on this thing, and then we'll bring Mike back in when we're ready to dyno the car and see if he's impressed.
Now, granted, this isn't a crazy build by any stretch of the imagination, but, nevertheless, we are taking care of some of the Mustang basics, starting off with this cold air intake here from Airaid, along with an exhaust from Flowmaster, wrapping it all up here with a BAMA tune. So intake, of course, you guys should know the deal by now with these. Gonna free up some power under the hood, give us a little bit more sound there. And the exchaust, of course, it's gonna help out with our 2015 GT because, as you may or may not know, these things are just ridiculously quiet from the factory, so Flowmaster should definitely open that up. So guys, we're gonna get started. I'm gonna get going here with the Airaid. Let's check it out.
All right, so Mike decided to go with the American Thunder Flowmaster Axleback Exhaust here, this 2015. Now, with any axleback here with these 2015s, you have to cut the factory exhaust. There's really no getting around it. So really not that big of a deal, though. Stan and I are making our measurements now. You really only measure about two and a half inches back from this bend here, make your marks, grab a Sawzall, something similar like that, and just make your cut. So we're about finished with our measurements now we're gonna start cutting.
Okay, guys, so we've just finished up with the install, the cold air intake and the exhaust here on Mike's 2015 GT. Of course, now the car's over here on the dyno jet. I got Paul from the BAMA Performance team in here with me, and he's gonna work on a tune to see what kind of power we can squeeze out of these mods. Now, we've been down this road a million times, of course. An intake and exhaust are pretty much standard operating procedure for a new Mustang owner. What kind of adjustments did you make with the tune?
Paul: With our tune, we make our standard adjustments, you know, throttle response, torque management, some fueling changes, a wide-open throttle for optimal power, as well as revised spark mapping.
Justin: Sounds great, man. Well, looks like you're pretty much buttoned up here, so I'll get out of the way and see what kind of numbers Mike can expect. All right, Mike, well, we just got done making our pool here with all the mods and the tune-up load. The bone stock car made 384, 362. Not too bad, of course. But Paul, what's the car making now?
Paul: After the Airaid intake, Flowmaster axleback, and our V2 race tune, the car put down 407 horsepower and 379 foot-pounds of torque.
Mike: Wow.
Paul: You know, over stock, that's 23 horsepower. It's pretty impressive.
Justin: Absolutely. Then you're looking at 26 horsepower, 30 pound-feet of torque underneath the curve, which is even more impressive. I mean, those are numbers you're gonna feel. Are you happy with those numbers?
Mike: Absolutely. I'm ready to feel them.
Justin: All right, well, I think you heard it from him. Let's get this thing off the dyno. Now, the power numbers are great, of course, but I think, most importantly, though, you're gonna be more concerned about the drivability and things like that. Right?
Mike: Absolutely. That's one of the big things I'm looking to get out of the tune.
Justin: Okay, well, there's only one way to find out, guys, so we're gonna unstrap this thing here from the dyno, get it out on the road and see what Mike thinks. Now, Mike, your first reactions, man, of how it feels, how it sounds. What are you thinking?
Mike: I'm telling ya right now. This is a dream come true. It is just absolutely amazing the power and the sound of the difference of just the Flowmaster alone and tune that I got.
Justin: Now, you were saying, like when we were pulling out of the parking lot, just right there you noticed the car was almost, like, shifting differently, but for the better. Right?
Mike: Yeah, absolutely. Right out of the factory, I notice it's a little jerky coming into the first, second, and third gear transition.
Justin: I hear ya. That's kinda gone now.
Mike: And I don't know what...whatever the tune did. I don't know if it's putting more fuel in or the airflow, but it's something connecting just right as it's firing.
Justin: Well, why don't you drop it down a gear and give these guys what they want?
Mike: Oh.
Justin: Yeah, buddy. This thing grips, man.
Mike: Oh, my god. Are you kidding me?
Justin: That top end, I feel, is a lot, you know, a little bit more robust now.
Mike: It just keeps pulling.
Justin: Yeah.
Mike: Everything about it is pulling, and it just wants to go.
Justin: Nice.
Mike: This car with this tune and everything that you guys have done to it, it's just...for me, this is American Muscle. This is what it's about. It's about having fun and having the power when you want it.
Justin: Nice.
Mike: You know what I mean?
Justin: Hell, yeah.
Mike: It's a little too tempting, but it is there.
Justin: Well, hey, tempting is always a good thing. It means you're joy-driving the car.
Mike: Got the self-control, but I'm gonna tell you now it's very hard.
Justin: Nice. All right, Mike, now, as far as the exhaust, what do you think with the Flowmaster? Are you happy with it?
Mike: Oh, I love it. It just gives you a much more throatier deep bass tone to it that is what a Mustang is about. It's got that sound. Just like its power, it's there.
Justin: Absolutely.
Mike: Once it hits that 3,000 rpm range, there's nothing... It's a Mustang.
Justin: Well, there you go, guys. I mean, it seems like Mike's a happy customer.
Mike: 100%.
Justin: He's loving life. And sounds like you'll be back for more mods, right?
Mike: Absolutely.
Justin: All right.
Mike: I'll be back.
Justin: That's what we like to hear. Well, guys, if you wanna stay tuned with more of Mike's build, you should know what to do by now. Be sure to subscribe to our YouTube channel, American Muscle Videos, and for all things Mustang, keep it right here at americanmuscle.com.
