Video Transcript

Regular viewers of this YouTube channel know I'm a fan of the Borla S-type muffler. I ran the S-type axle-backs on my twenty eleven mustang, and the s-type cat back is the current system of choice for my 2015. Many of you have asked though what the axle-back's going to sound like on the 15 if you keep the factory resonator. So today we're going to install the s-type axle-back on my 2015 and give you some sound clips. I've always liked the s-type muffler because it gives you a nice aggressive sound on wide open throttle but is very tame for cruising and offer no drone whatsoever. Just like the cat back system, the Borla S-type axle-back is available in your choice or either a polished or a black four inch tip.

For this installation today, a lift or a jack and jack stands, half inch ratchet, 15mm socket, tape measure, marker, sawzall and safety glasses.

Like many other axle-backs we've already shown you, this one's going to cut in right back here behind the axle. Because it is an axle-back system, this is going to fit your fast back or convertible. Just follow the curve until it ends, I'm going to measure over two inches from the end of the curve, mark, and cut.

Once it's cut now, slide it off the hanger. Once you have the pipe cut off, the installation's very easy. You slide it up into the rear hanger first, line the pipe up, and slide it over. Tighten the clamp and repeat the process on the other side.

Now let's see how our S-type axle-back sounds. Very similar sound to the cat back, I thought it would, a little less volume but very similar tone. Right out of the box, the Borla S-type has the sound I kind of expected the axle-back to have. It's got a similar tone of the cat back, just less overall volume. It sounds really good in it's own right, and probably if you put it one of our H-pipes sound even better.

Just like all Borla's now, now we're cruising at 2000 RPM, 65 miles an hour on the highway, zero drone, don't even know it's back there. Give it a little gas, it wakes up, but cruising speeds you can drive all day and not even know its there.

Overall, the S-type, again I'm still a fan. It's a good sounding muffler if you want something that has a nice rich tone, really sounds good when you get on it, but no drone on the highway, nice and quiet, it's an excellent choice. Like all the axle-back systems you have to cut to put it on, but overall the installation's pretty simple, takes about an hour to do so you can be back on the road in no time.
