For those who demand the best in performance and durability, Borla now offers a cat-back exhaust system for your Honda Civic SI Coupe and Sedan. Constructed from T-304 aircraft quality stainless steel, this system features ultra-smooth mandrel bends to ensure maximum flow and power as well as precision CNC manufacturing for that perfect bolt-on fitment. Twin stainless steel tips emblazoned with the Borla logo will let other enthusiasts know that you only treat your Si to the best in performance modifications.

With the added security of Borla's Million Mile exhaust warranty, you never have to worry about your Civic Si having a junk exhaust. Borla offers catbacks for the Civic Si Sedan and another for the Coupe. Both the Si Sedan and the Couple catbacks use a smaller than stock, oval muffler with less baffling for higher exhaust flow and a more aggressive sound. Borla keeps a resonator in line to reduce the buzzy, raspy notes as much as possible. Both the Si Coupe and the Sedan exhaust systems attach to the stock Honda catalytic converter using slip fit piping and the included pipe clamps.
