$973.14 $1,390.20
$973.14 $1,390.20

Fits 2006-2011 Honda Civic Si 4-door sedans, including the 2008 MUGEN Si.

The Invidia Q300 cat-back exhaust system is engineered to provide a significant performance upgrade for the 8th generation Civic Si sedan without the harsh, raspy tone often associated with aftermarket systems. The Q300 features a unique flat-bottom muffler design that aids in high-speed aerodynamics while the internal continuous strand glass wool packing delivers a deep, mellow exhaust note. Built from mandrel-bent SUS304 stainless steel, this system optimizes exhaust flow and reduces backpressure for improved throttle response and power gains.

  • Constructed from high-quality SUS304 stainless steel for long-term durability and corrosion resistance
  • Mandrel-bent piping ensures consistent diameter throughout the bends for maximum flow
  • Cast flanges provide a precise, leak-free fit to factory or aftermarket headers
  • Robotic TIG welding for superior strength and a clean aesthetic finish
  • Includes all necessary gaskets and hardware for a straightforward bolt-on installation
  • Manufacturer Part Number: HS06HC4G3S
