2023 BMW XM 4.4L Twinpower Turbo V8 w/ X-Pipe & Borla ATAK!Added:
All right, guys. Guess what we got in here? Look at this beast. 2023 BMW XM fully wrapped, fully customized. It's a sick, sick beast. Check it out. It's a V8 with a hybrid motor also. You know what we're going to do? We're going to straight pipe it because you know what?
Why not? Here's the big muffler that that's on it. I love the tip setup on it. Check that out there and there. And I drove it in the suede and everything.
It's beautiful. It has ambient lighting and everything is sick. Just a sick sick vehicle. It's got a self-healing wrap on it. This is not the original color of it, but it still looks sick. There's the muffler on it there. It's got a valve in there and then a regular. So, we're going to to do a muffler delete. We'll just weld them together and put a a brace and then just connect it to one of them on each side. We'll show you guys after we take it off. But that's it right there. And then it's got a factory Hip double cats uh secondaries and primaries. Okay, let me show you guys the front of it. It's like a futuristic BMW. That's the BMWs I'm used to from the past where like they outdo everybody. Really good looking car. BMW XM. All right, stay tuned, guys. We're going to let you guys hear a before. So, the nice thing about this thing, guys, he already has the valves open and he took the the fuse out, so it keeps the valves open. So, this is what it sounds like with valves open.
There we go. Much better. Thank you.
So, you got to press the X1 button twice.
and it activates the motor.
So, there's the idle on it. It's running at 88.
Going to rev it again.
That definitely needs more.
One more.
right in 93.
Yeah, it definitely needs more. One more. Go ahead.
93 again.
Okay. 97 when it pops. Stay tuned, guys.
We're going to change that. It's a massive muffler. Look at this thing. It is massive. How much space it opened up when we took it off. It's crazy. Now we have space for days. First thing we're going to do is we're going to test out straight pipe with no mufflers or whatever to see what it sounds like. And then we might do a crazy contraption with an Xpipe as you guys can see and Borla attacks and Borla S types. We don't know yet. We're going to figure it out. Stay tuned. This is what straight pipes sound like, guys.
So idle is 72.
All right, give me gas.
Not bad. Here's sound decibb. Go ahead.
It opened up to 99 again.
101 again.
All right. So, that's what straight pipes sound like. Stay tuned. So, now we're going to test out the Carbon R for you guys. Here we go. Go ahead.
BMW XM.
That's idle. Give it a guess.
Whoa, that sounds good, too. Again.
That pop is more refined. You know what I said? Again, your sound dec.
One more. They're getting hot.
All right. Next, we're going to test out the Big Boss fours.
Big Boss fours. Here we go. Go ahead.
Oh, I like that. That has more pop again.

>> Holy crap. That my ears ringing. One more.
That might be the one. Big boss for wars. Guys, we can't forget about Black Widow. So, here's Black Widow. Go ahead.
One more.
That's not the one. I think big boss is the way to go.
Here's sound decibels. Go ahead.
Right at 104. One more.
You guys let me know what you guys think in the comments on this BMW XM. Guys, when I tell you we do really crazy custom work, check it out, guys. It's the first XM that you guys going to see with this crazy setup with a Bortal attack system. Look at that. Tell me that ain't a crazy design. Check it out.
So, they come into the Xpipe, then they go back out into each Borla attack and then into the tips. That is so beautiful. Work of art, guys. So, after a couple hours, guys, it's finally done.
The BMW XM. Are you guys ready to see what we did? the Frankenstein contraption of beauty. So, here it is.
So, we got it off each motor on each side. It's got an H pipe in the front.
Then, we ran it into an Xpipe and then ran it back out into two Borla Attacks.
Nothing else fits as beautifully as the Borla attacks on this car with the sound profile. So, there it is. And there's the two tips on each side like nothing ever happened. We put everything back on it beautifully. Here's the part number on the Borla Attack 400832.
There'll be a link in the description, but there it is. So, let me know guys what you guys think of the sound once we started. And if you guys don't know about this car, this thing pushes around 700 horsepower. It's a hybrid and 50 VH system. So, it's really nice, really beautiful car. All right, so stay tuned guys. We're going to let you guys hear.
Hope you guys like it. And there's the rest of the system. There's the H pipe there. There's the two cats. And the main one still there. Okay, so the whole system is all still everything else is the same. We just took off that massive muffler and replaced it with two beautiful Borla Attack mufflers. All right. And an X bite. There's the stock muffler that was on it. That huge beast we just took off. So, here we go. BMW XM 5.0 L with Borla Pro XS.
The first cold start. Going to let it warm up a little bit.
That's what it sounds like with a cold start.
>> So, that's not going to be annoying in the morning. It's not too loud. That's good.
The nice thing about lights, you hear it when you hit the gas. So, you hit it.
So, it's right at 84 81. It's going down.
All right.
Let it warm up a little bit. Go ahead.
It's about >> better.
>> A lot better.
>> Is it clean?
>> Exactly. Or you want it louder?
>> Well, you tell me.
>> We You It's your car.
>> How do you make it louder?
>> We can take the H pipe out that's in the center.
>> Yeah.
>> We'll leave it there.
>> You want to drive it down the road real quick? Yeah.
>> All right.
When you heard the pop, you're like, "Yeah, I'm going to do like that again."
>> Yeah. There's that pop. You're like, you were waiting for that one, right?
>> Yeah.
Again, so sick. One more.
Go ahead and back it out. If you guys don't know, we are located in beautiful Nashville, Tennessee. There's a beautiful shop right there, right down the street from Skyline Hospital on Vicki Pride.
Back to the action.
