HKS 17+ Honda Civic Si Sedan (FC1) Hi-Power Muffler Exhaust Read reviews

The HKS Hi-Power Exhaust is made in Japan by one of the most beloved JDM aftermarket tuning houses. Starting after the front pipe, this exhaust system is 65mm/2.5" all the way to the back where it enters into a single muffler, and then exits out of the Dual 97mm/3.8" tips with a burnt titanium finish. 

Manufactured with the industry standard 304 Stainless Steel. In terms of sound, expect around 67 decibels at idle (OEM = 58 Decibels), and 92 decibels at the highest (OEM= 82 Decibels) with the stock downpipe and front pipe.
