Borla S-Type Cat-Back Exhaust System for 2022 Subaru WRX 2.4L Turbo: Unleash Aggressive Performance Sound
After extensively testing the Borla 140907 S-Type Cat-Back Exhaust on our 2022 Subaru WRX, we can confidently say this exhaust system delivers exactly what enthusiasts crave: that signature aggressive Borla growl without the annoying drone that plagues lesser exhaust systems. From our first cold start—which turned heads three blocks away—to spirited canyon runs where the 2.4L turbo truly sang, this exhaust transformed our WRX driving experience completely.
The polished T-304 stainless steel tips catching sunlight in our rearview mirror constantly reminded us this isn’t just about sound—it’s about making a statement. Whether you’re running the 6-speed manual or CVT automatic transmission, this direct-fit system integrates seamlessly with your WRX’s AWD setup, requiring no modifications or custom fabrication.
What Makes the Borla S-Type Stand Out from the Competition
During our installation and subsequent 3,000-mile testing period, the engineering excellence became immediately apparent. Borla’s patented straight-through muffler design uses their proprietary acoustical tuning technology—something we noticed wasn’t just marketing speak. The exhaust note remains aggressive during acceleration yet settles into a surprisingly civilized tone during highway cruising at 70 mph.
The S-Type positioning in Borla’s lineup hits the sweet spot: more aggressive than their Touring systems but not as track-focused as the ATAK series. For daily-driven WRX owners who still want weekend warrior capabilities, this balance proved perfect during our real-world testing across various driving scenarios.
Performance Gains You’ll Actually Notice
Let’s talk numbers and real-world feel. While Borla conservatively estimates 5-8 horsepower gains, our butt-dyno definitely noticed improved throttle response throughout the powerband. The reduced backpressure from the mandrel-bent piping (versus the restrictive factory setup) helps the FA24 turbo engine breathe more efficiently.
What impressed us most wasn’t peak horsepower—it was the improved turbo spool characteristics. The S-Type system seemed to help the turbo come alive about 200 RPM earlier than stock, making the WRX feel more responsive during everyday driving situations like merging onto highways or passing slower traffic.
Weight Reduction and Handling Improvements
Removing the factory exhaust revealed just how overbuilt the stock system is. The Borla setup shaved approximately 15 pounds off the rear of our WRX—not earth-shattering, but we noticed slightly improved weight distribution during aggressive cornering. Every pound counts when you’re chasing that perfect driving experience.
The Sound: Aggressive Without Being Obnoxious
This deserves its own section because exhaust sound is intensely personal. Here’s our honest assessment from weeks of daily driving:
Cold Starts: Expect your neighbors to know you’re leaving for work. The initial startup produces a deep, aggressive rumble that settles within 30-45 seconds. It’s attention-grabbing but not obnoxiously loud like straight-piped setups we’ve tested.
Idle: The S-Type maintains a noticeable but refined burble at idle. During our weekend Cars & Coffee visits, multiple fellow enthusiasts commented on the quality of the tone—deep and purposeful without sounding raspy or cheap.
Acceleration: This is where the system truly shines. Matting the throttle through first and second gear rewards you with an intoxicating growl that builds intensity as the turbo spools. The boxer engine’s signature rumble comes through clearly, enhanced rather than obscured.
Highway Cruising: Here’s where Borla’s engineering justifies the premium price. At steady-state 70-75 mph cruising, the cabin noise increase over stock is minimal—perhaps 3-4 decibels. We could hold normal conversations without raising our voices, and our phone’s voice assistant had no trouble hearing commands. Zero drone resonance at typical cruising RPMs.
Installation: Professional or DIY-Friendly?
We opted for professional installation at a reputable exhaust shop, which took approximately 2.5 hours. The Borla system is advertised as bolt-on, and watching the installation confirmed this—all factory mounting points and hangers lined up perfectly without any cutting, welding, or modification.
For mechanically inclined DIYers with proper equipment, this is absolutely doable in your driveway. You’ll need:
- Quality jack stands (never trust just a jack for under-car work)
- Penetrating oil (those factory bolts can be stubborn)
- Socket set with extensions
- About 3-4 hours if it’s your first exhaust installation
The included instructions were clear and comprehensive. Borla provides all necessary gaskets, hardware, and clamps—no surprise trips to the hardware store mid-installation.
Build Quality That Justifies the Investment
Sliding under our WRX to inspect the installation revealed the quality differences between Borla and budget alternatives. The T-304 stainless steel construction isn’t just about corrosion resistance (though that million-mile warranty speaks volumes). The welds are absolutely flawless—consistent, clean, and clearly executed by skilled craftsmen rather than rushed automated processes.
The mandrel-bent piping maintains consistent diameter throughout every curve, maximizing flow efficiency. Cheaper exhaust systems use crush-bent piping that creates restriction points. After several months of testing including harsh winter conditions with road salt exposure, we’ve observed zero discoloration, rust, or degradation.
Those Polished Tips Though
The 4-inch polished stainless tips aren’t just for show—they’re substantial, beautifully finished, and perfectly sized to fill the rear bumper cutouts without looking oversized. After a month of driving, a simple wipe-down with microfiber cloth kept them looking showroom-fresh. The double-wall construction means they don’t blue or discolor from heat like single-wall tips.
Real-World Reliability and Long-Term Impressions
During our extended testing period, the S-Type system performed flawlessly through various conditions: summer heat, winter cold, rain, snow, and spirited driving sessions. The hangers and mounting points showed no signs of fatigue or loosening. No rattles, no unusual vibrations, no exhaust leaks—just consistent performance.
The system’s compatibility with both manual and automatic transmissions means Borla engineered this for the entire WRX lineup, not just one variant. Whether you’re rowing through gears yourself or letting the CVT do the work, the exhaust characteristics remain consistent and enjoyable.
