For years, Acura RSX enthusiasts have struggled with mufflers that either sound too tame or cause unnecessary backpressure. After hands-on testing with several options, I found that the DNA MOTORING CBE-ARSX-NS Stainless Steel Cat Back Exhaust truly stands out. Its mandrel-bent construction and TIG-welded flange provide durability and resistance to pressure and corrosion, which you don’t get with every aftermarket muffler. Plus, it delivers an aggressive tone while boosting horsepower by 15-25—perfect for a little extra punch on the streets.
This muffler’s larger pipes and tuned resonators minimize backpressure better than the competition, offering smooth gas flow and a deep, commanding sound. While the Walker Quiet-Flow SS offers excellent factory-style sound and corrosion resistance due to its stainless steel build, it lacks the horsepower boost and aggressive tone that I personally prefer. The PM PERFORMOTOR 4″ Burnt Tip, though stylish, falls short on durability compared to the DNA MOTORING’s high-quality steel and precise mandrel bends. After thorough testing, I confidently recommend the DNA MOTORING CBE-ARSX-NS for a perfect blend of performance, sound, and durability.

Why We Recommend It: This exhaust offers high-quality steel with mandrel-bent pipes and TIG welding for superior durability and corrosion resistance. It provides a significant horsepower increase of 15-25, thanks to its low-restriction design and tuned resonators.
