Invidia Catted Downpipe – 2017-2020 Honda Civic Type R

Catted Downpipe for the 2017-2020 Honda Civic Type R FK8

The Invidia Catted Downpipe for the 2017-2020 Honda Civic Type R FK8 replaces the factory downpipe on the K20C1 2.0T with a 76mm high-flow stainless unit. The FK8’s factory downpipe is a significant restriction in the K20C1’s turbocharged exhaust path, replacing it produces meaningful improvements in turbo spool, throttle response, and power while maintaining catalytic function.

DETAILS

• 76mm piping
• High-flow catalytic converter
• 304 stainless

The K20C1 responds to downpipe work with improved boost build and throttle response. The high-flow cat maintains emissions compliance while eliminating the factory restriction.

Why Choose Invidia

Invidia has been manufacturing performance exhaust systems in Japan since 1999, and in that time they have built a reputation that carries real weight in the tuning community. Every system is manufactured using SUS304 stainless steel and mandrel-bent tubing, which eliminates the flow restrictions and weak points that crush-bent alternatives introduce at every corner. Their in-house engineering team designs each application from scratch rather than adapting a generic template, which is why Invidia fitment is consistently tighter than the competition. The result is an exhaust that installs cleanly, seals correctly, and lasts. Invidia backs their products with a quality standard that is visible in the finish, the weld quality, and the hardware, details that reflect over two decades of refining the same core manufacturing process.
