Product Description
The new 2017+ Honda Civic Type R is a special vehicle that deserves a premium GReddy exhaust. Keeping with the SP tradition of a street performance exhaust, careful attention to both sound and performance was considered in the design of this system. The free flowing straight-though exhaust on the CTR’s turbocharged K20C1 engine netted just 88 dba on our standardized revving sound test with an amazing 16whp increase on the GReddy dyno.

Large diameter, stainless-steel, 3-inch mandrel-bent piping is tucked up in the FK8 Civic Type R chassis to a larger specially shaped SP oval muffler, to maximize flow and control the sound quality. The Civic Type R’s rear diffuser exhaust opening is elegantly completed with a special GReddy Supreme SP badge, between the dual 4.5” SP tips.

  • Honda Civic Type R [FK8] (2017, 2018, 2019, 2020, 2021)


  • Full 3 inch straight structure to improve exhaust flow
  • Tested and JASMA approved for sound and quality

  • Back-pressure reduced via larger 3 inch piping
  • Carefully designed to be sound compliant without the need of a resonator
  • Cat-back system includes midpipe
  • Center exit design with dual double walled polish tips
  • Designed to eliminate exhaust drone
