The MagnaFlow 19420 cat-back exhaust system, designed specifically for the Honda Civic Si Coupe 1.5L with dual center exit, can potentially add 5 to 15 horsepower. By enhancing exhaust flow and reducing back pressure, this stainless steel system improves engine efficiency and performance. The actual horsepower gain from the MagnaFlow Civic Si exhaust may vary depending on other modifications and the vehicle's overall condition, but it remains an effective upgrade for those seeking enhanced driving dynamics.
