Discussion on Axle-Back Exhaust 11978CB
I’ve had the BORLA 11978CB Axle-Back System installed on my 2022 Ford Bronco for three months and I must say, the performance improvement is substantial. The all-welded T-304 stainless steel construction contributes to both the longevity and weight reduction of the system.
In my real-world tests, the exhaust showed a noticeable reduction in back pressure, which I measured to be about 10% lower compared to the OEM system, resulting in better throttle response. I also recorded a sound level increase of 12 dB at wide-open throttle, adding a rich, throaty sound that is quintessentially BORLA without being annoying on long drives.
u/ExhaustExpert: I’ve read about the sound comparison with other systems. How does it stack up against competing brands like Flowmaster or MagnaFlow?
u/PerformanceGuru: Great question! In my comparison, the BORLA offers a deeper, more resonant tone, while Flowmaster tends to produce a more metallic sound that’s less appealing to some users. My neighbor has a Flowmaster on his Bronco, and both of us agree that the BORLA wins in terms of sound quality.
While the up-front cost of the BORLA 11978CB ($1279.80) may seem steep, I’ve been exploring its long-term value. Given its lifetime warranty and T-304 stainless steel construction, which resists corrosion far better than mild steel, I’m convinced it’s a sound investment for the long haul.
In fact, I’d seen a similar system from another brand that offered only a one-year warranty for about $900. If I calculate the possible maintenance costs over time, the BORLA system likely pays for itself within three years, even if I factor in installation costs.
u/ExhaustFanatic: Interesting take! Have you had any rust issues or sound degradation over time with the BORLA?
u/ValueSeeker: Not at all! It’s been holding up beautifully in various weather conditions. No rust or changes in sound quality; the performance seems consistent.
I took my 2023 Bronco equipped with the BORLA 11978CB on a weekend off-road trip to Moab. In rugged terrain, I specifically noticed an improvement in low-end torque, which helped me navigate tricky inclines. I measured a drop from 2000 RPM to around 1700 RPM when climbing, indicating better performance than the stock exhaust.
Additionally, the weight savings of roughly 15 pounds compared to the OEM unit made the vehicle feel more agile, which was especially noticeable when making tight turns.
u/RoadWarrior: That’s impressive! Did the increased exhaust flow affect fuel efficiency at all?
u/TrailBlazer: It did actually! I saw a slight improvement in gas mileage of approximately 1-2 MPG on highways, pushing my Bronco over the 20 MPG mark.
Diving into the technical features of the BORLA 11978CB, the flow dynamics are specifically engineered to enhance performance. During a dyno test, I recorded a peak gain of +12 horsepower and +15 lb-ft of torque at approximately 3000 RPM compared to the stock system.
The unique pipe routing design and muffler technology allows for optimal exhaust flow, which significantly contributes to those numbers. Engineered precision plays a critical role here; each component is designed with a purpose, rather than standardization common in mass-produced kits.
u/MufflerMaster: Those figures are excellent! How does it hold against the competition in terms of performance metrics?
u/TechWhiz: From my comparisons, many competing systems barely reach +8 HP, putting the BORLA firmly at the forefront in terms of build quality and performance numbers.
If you’re considering the BORLA 11978CB Axle-Back System, pairing it with high-performance headers can dramatically enhance exhaust flow even further. After using aftermarket headers designed for the Bronco’s 2.7L, I noticed a further 5-6 HP gain on the dyno, as well as a richer exhaust note.
Additionally, I recommend utilizing a proper tune after installing the system. It optimizes fuel mapping to complement the increased airflow, ensuring your Bronco performs at its peak with the new setup.
u/TunerGuy: What about swapping out the catalytic converter? Would that interfere with legality or warranties?
u/AccessoryAddict: It can be a tricky area! If you’re looking to replace the catalytic converter with a high-flow option, be sure to check local regulations. The warranty on the BORLA system should remain intact, but it’s always wise to keep documentation and check with the manufacturer for peace of mind.
Having installed exhaust systems from multiple brands, including MagnaFlow and Flowmaster, I decided to directly compare these with the BORLA 11978CB. Notably, the sound profile of the BORLA stands out with a cleaner, more sophisticated tone, particularly noticeable at lower RPMs.
Furthermore, the build quality of the BORLA, particularly its welds and finishing, surpasses its competitors. After measuring the thermal expansion rates during high-performance runs, I found that BORLA exhibited significantly less fluctuation in performance metrics, leading to more consistent outputs.
u/ExhaustSkeptic: Are there any downsides? I’ve heard some complaints about drone with the Flowmaster products.
u/ComparisonKing: While the BORLA does have a mild drone under certain circumstances, it’s far less intrusive than what I’ve experienced with Flowmaster. The drone is mostly absent under normal driving conditions, appearing only during aggressive acceleration, which is typically expected with performance exhaust systems.
