As much fun as this car is straight from the factory, the long awaited release of Vibrant’s new STREETPOWER Cat-Back Exhaust
System for the 2006+ Civic Si (Part #1626) makes this car even more fun to drive.
Manufactured entirely from T304 Stainless Steel, this exhaust system features 2.5” diameter CNC mandrel bent exhaust tubing
for optimum exhaust flow and the type of impressive power gains
you can feel. Independent Dyno Testing showed that this exhaust system produced gains of 10HP and 8 ft/lbs at VTEC on a vehicle that was otherwise completely stock.
Like all STREETPOWER exhaust systems, this cat-back features Vibrant's "True Straight Through" internals to help produce a low, deep exhaust note (which complies with California’s 95db exhaust noise legislation). The exhaust gases exit through a 4" angle cut tip, giving the system an "almost stock" appearance from the rear view.
