    Will It Fit Your Vehicle?


    Megan Racing Down-pipe for the 2006 to 2011 Honda Civic SI made of durable 100% T-304 Stainless Steel and is polished to a mirror-like finish. This Down-pipe replaces the OEM exhaust piping with all of its restrictive bends while increasing the inner diameter of the pipe; this greatly increases the exhaust flow and reduces the turbulence within the OEM exhaust system, freeing up high-end horsepower and mid-range torque.

    Expect an increase in exhaust note due to freeing up the exhaust flow. The missing link to your exhaust system; this down pipe will give you that competitive edge that you have been looking for. (NOTE: The test-pipe is for off-road use only and is not intended for public highway use. o2 Simulators may be required if a CEL is triggered.)


  • 100% T-304 Stainless Steel Piping TIG-welded to CNC-machined flanges for long-lasting strength and durability

  • Smooth bends improve flow and performance.

  • 2.5" straight-through piping

  • Resonator included to control noise levels

  • Note: All Megan Racing Exhaust and Suspension products are deemed for "off-road use only"-- please check local laws regarding the modification of the exhaust systems by checking the vehicle code for your state. Many states are more stringent on exhaust modification laws and to pass SMOG. Please check your local laws.
