Megan Racing Down-pipe for the 2006+ 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
