Installing A Borla X-Pipe Raptor System

When Borla designed their X-Pipe with Mid Pipes Muffler Replacement Exhaust System for the new ’18 Ford Raptor, they saw that they could improve on the stock unit both in terms of performance, and perhaps equally as important, in the way the truck sounds.

Unless they’re slipping, everyone now knows that the Ford is now powered with 3.5L EcoBoost V-6. With its twin-turbos, direct injection, and 450-horse rating, it’s an engineering marvel. Any turbo V-6 is going to be a spinner (that’s why Ford came up with a 10-speed transmission), and the EcoBoost has its own distinct rev pattern, producing its sound accordingly. The Raptor used to come with a V-8 with everything a V-8 entailed. We’re not going to lie; we liked the V-8. Better than the new Eco, you ask? That depends on what we’re doing with it at the time. Freeway blasting? Eco. Off-road grunting? V-8. But, that’s just us.

Being long-time racers, Borla’s performance aims were to add an X-Pipe section just off the initial collectors and then a nearly combined resonator and muffler section that’s way better designed than the stock unit. Borla claims they were able to achieve a 13 percent increase in flow, while reducing the overall system weight 18 percent. That weight savings is by the use of aircraft quality T-304 stainless steel, and the Borla unit is way lighter than the stock unit — and those are numbers we can believe. The stocker is the size of a trashcan and weighs as much as a dumpster, so anything would be an improvement. It’s also fairly quiet.

The flow increase is due to the X-pipe that blends well and the internal design of the muffler, which is pretty straight-through. Borla tries to separate the sound waves from the exhaust, but thinks its best to leave the spent gas flow alone. Borla offers the pipes that go after the muffler too, but this owner just used the stock ones.

That trapped sound is what’s important. The Eco’s not a V-8, so it won’t sound like a V-8, but the Borla is pretty crackly. Go to to watch the video of the install. We have a before-and-after sound comparison, so you can hear it for yourself what the Raptor sounds like stock and with the Borla unit. And know that this is the S-Type Borla system — they make an ATAK system that’s even louder.

The install is pretty easy, especially on a new truck, so this is one that you can do yourself — with the help of a friend. Unless you’re built like the Rock, it’s a two-man job really, so plan accordingly.

Safety (and just plane room to work) first, and the Raptor is jacked up and stands used to get the back end off the ground.
The stock resonator.
The stock muffler.
WD-40 is used on all of the connections and rubber isolators.
Every joint is loosened up starting at the front and working back.
With the rearend up off the ground, there’s plenty of room to work with.
Rather than try to slide the isolators off the posts, the post brackets are simply removed.
The last sections are loosened.
There are isolators securing the tips of the system, so they too are removed.
With the help of a rubber mallet, the passenger-side final section is removed.
Next, the driver side is pulled.
Working forward, the muffler and resonator sections are pulled.
The first step on the installation of the Borla unit is to apply antiseize to the pipes.
The X-pipe is installed.
The connections are made, but left slightly loose at this point.
Since the Raptor is a crew cab model, extension tubes are added between the X-pipe and the muffler assembly.
More antiseize is applied to the connections.
The Borla muffler assembly is lifted into place.
With WD-40 on the probe, the isolator is slipped on and bolted into place.
The rear tip sections are installed.
The two isolators are installed.
With all the pieces in place, the hardware is tightened up. Care is taken to position the tips equally from the bottom edge of the bumper when doing so.
The X-pipe really helps with equaling out the pressures in the exhaust system.
With the Borla S-Type mufflers in place, the system will have much more free-flow tendencies, and will sound better to boot.
