Performance Axle-Back for Cars: In-Depth Discussions
I’ve been testing the BORLA 11890 Axle-Back Performance Exhaust System for my 2018 Ford Mustang EcoBoost. Here’s my detailed analysis based on both track and daily driving experiences.
Upon installation which took approximately 30 minutes, I measured the sound levels before and after using a decibel meter. Before installation, idle levels were around 74dB, but with the BORLA system, it jumped to 85dB—making it significantly more aggressive without being unbearable. Additionally, the build quality is exceptional; I noted T-304 stainless steel materials resist corrosion remarkably well, which adds to its longevity. I’ve experienced a noticeable power increase—an average of 10-15 additional horsepower at peak RPMs during my dyno runs.
Thanks for sharing your insights! I’m thinking about whether this exhaust would fit my driving style. Did you notice any difference in fuel efficiency?
Great question, u/TrackJunkie! While my fuel efficiency did dip slightly when pushing the car on the track, I’ve seen better economy in daily driving—about 1-2 MPG improvement on highways with the exhaust at cruising speeds. It seems the exhaust helps the turbo spool better, which allows for more efficient combustion.
I’ve been looking at various options for my Mustang, and I’d love to know how this system stacks up against others like Flowmaster and MagnaFlow.
In my research and personal experience, I find that the BORLA system stands out in sound quality and material durability. While Flowmaster has a more aggressive sound for muscle cars, it can be louder and may drone at highway speeds. On the other hand, MagnaFlow offers a mellow tone that might not appeal to those looking for that classic performance growl. The BORLA 11890 achieves the perfect balance—it’s loud when you want it but smooth during daily commutes.
u/CarLover88, excellent points! I also feel that the installation process is crucial; BORLA systems typically have a more straightforward bolt-on design compared to some competitors, which eases the whole setup. Plus, the retention of factory fitment and OEM compatibility enhances my trust in BORLA as a brand—definitely recommend giving it a shot!
Just wrapped up a weekend of spirited driving and put the BORLA 11890 through its paces. Let me share some experiences that might help those considering this upgrade.
First off, acceleration felt sharper, aiding my times on the track by nearly 0.2 seconds compared to stock. On a closed circuit, I recorded a decrease in lap times while the responsiveness of the EcoBoost was substantially improved with the less restrictive exhaust. Notably, I also experienced an improved throttle response and reduced turbo lag, especially noted during corner exits. However, the trade-off is a slight increase in cabin noise, which could be a deal-breaker for some.
Thanks for the insight, u/SpeedAddict! Do you think the setup is suitable for daily driving, or is it strictly for performance? Would love your take on daily driveability given the volume levels.
Great question! While it’s definitely louder than stock, I found it still manageable for daily use—especially with all windows up. If you enjoy a more exhilarating drive without compromising comfort, then this system is a solid choice. Just be prepared for some stares at stoplights and keep aware of local noise regulations!
As an analyst focusing on automotive upgrades, I’d like to discuss the long-term value of investing in the BORLA Performance Exhaust 11890.
The MSRP at $799.99 may seem steep initially, but considering the long-term durability and enhanced performance benefits, I’d argue it delivers excellent value. The T-304 stainless steel construction will safeguard against rust and wear over the years, potentially outlasting less expensive options significantly. Also, the improved horsepower and torque can enhance the resale value of your Mustang, influencing a future sale since performance aftermarket parts are increasingly sought after in the used market.
Solid points, u/ValueHunter! I’ve been considering going for this one primarily due to its build quality. Does it retain value over time compared to other systems you’ve looked at?
Excellent question! In my studies, models like Borla generally retain more value owing to their reputation among enthusiasts. While cheaper exhausts might attract more buyers initially, Borla’s strength and sound quality tends to have a loyal following, ensuring a quicker sale at a higher price when you decide to part ways with your vehicle.
Diving into the technical aspects of the BORLA 11890, I want to focus on measurable performance data that advocates for its effectiveness as a high-performance exhaust system.
With a 2.25-inch piping diameter, the system minimizes back pressure effectively—leading to improved overall efficiency. In my testing, the system produced an average of 8% more torque across the RPM range compared to stock during back-to-back runs on the dyno. The system’s all-welded construction ensures seamless airflow, which I noticed markedly in acceleration testing. When I switch back and forth with different tunings, results consistently show that the BORLA system lifts the car’s performance ceiling significantly. It is noteworthy to mention, however, that its overall weight is slightly heavier than stock by about 5 pounds—this is a trade many performance enthusiasts are willing to accept for the sound and gains.
Really valuable insights, u/TechieAuto! Do you think the weight difference has a noticeable effect when tracking? What’s your experience?
Excellent question! In most cases, the slight weight gain is offset by the improved power output and throttle response. During my timed laps, I found the performance boost outweighed the minimal weight increase, contributing positively to overall lap times. For those illusioned by the weight on a track, I’d recommend considering lightweight wheels or further modifications to improve acceleration without excess expenditure.
