This is the full 3" Exhaust cat back exhaut for the 8th Gen Honda Civic Si.


This is designed to work flawlessly with our Turbo Kit that has the 3" Downpipe and Test Pipe transforming your car to a full true 3" exhaust system.


It comes standard with two unequal resonators, we used unequal resonators to dampen different frequencies of resonation from the cabin that is common with most other 3" exhaust systems insuring that you gain maximum performance without sacrificing the luxury of a quiet cabin. Our resonators are made by Vibrant assuring you a superior quality product.  All the bends are smooth mandrel bent from 3" Stainless Steel for superior flow and maximized performance gains.
