Description

The Invidia Q300 Cat-Back Exhaust for the 2006-2011 Honda Civic Si Coupe (FG2, K20Z3) is the daily-driver favorite: deep and refined at cruise with a clean VTEC wail at full throttle. Built from 70mm mandrel-bent SUS304 stainless steel with CNC-machined flanges and robot TIG welds, its flat-bottom muffler uses continuous piping and Advantex material for free flow with optimized back pressure and very low drone. A 110mm rolled stainless tip finishes the system. Coupe-only fitment.
