California Prop 65 Warning
Upgrade your 2017–2021 Honda Civic 1.5T with the EOS High Flow Cat / Catless Downpipe. Cast from T-304 stainless steel with a brushed silver finish, this race downpipe opens from a 3.75″ cast inlet down to a 3″ cast outlet for virtually turbulence-free airflow — one of the most effective bolt-ons for the 1.5L turbo four, especially paired with an ECU tune like Hondata or KTuner. Choose W/ Cat or Catless above.
