It's no secret that an upgraded performance downpipe makes a world of difference on any 2017+ K20C1 equipped Honda Civic Type R.

We took a look at the current setups on the market and said, "we can make it better" and the 27WON high flow downpipe was born.

A CAD-optimized design, dyno-proven power gains, T304 stainless steel construction, and OEM-like fitment make this downpipe the perfect setup for your next exhaust mod. Check out the full details below and see how we REDEFINE the 27WON Civic Type R catted downpipe.

27won redefine subheadline


An wide inlet size on our performance downpipe creates the optimal flow scenario allowing hot exhaust gasses to quickly escape from the turbine side providing increased turbocharger efficiency and response. This is also the largest diameter drop-in downpipe on the market for the CTR meaning better flow than other units that market themselves as high-efficiency. #Facts!

Speaking of turbos, we designed our downpipe to match up perfectly to the stock turbo in your FK8 or FL5 Type R or our sick "Kuro" upgraded turbo. This downpipe will also mate up to most any aftermarket drop-in turbo out there meaning you've got options.


The 27WON performance downpipe is cast from T304 stainless steel. This stainless-steel variety is not only strong, but offers the perfect finish for aesthetics and ultimate durability.

We then precisely TIG weld each cast section of the downpipe to the catalytic converter body ensuring a leak-free connection.


We designed our downpipe to retain all the OEM pick-up points to be able to re-use the stock heat shields . When it comes to heat, we want to keep it out of the engine bay as much as possible so re-using the stock heat shields is a no-brainer. Also included are all the nuts, bolts, and studs for a seamless installation the first time.


Power, we all know that’s what you’re here for. All of our dyno testing was conducted using a Dynapack chassis hub dynamometer with our 2018 Civic Type R outfitted with a suite of bolt on modifications.

Over a 6 dyno run average, the 27WON downpipe measured over 10 WHP and 28 LB/FT more torque than the stock Honda downpipe. In our best run, we saw more than 33 LB/FT of torque over stock!

  • 27WON Performance downpipe = green line


For optimum exhaust velocity the 27WON downpipe upgrade comes equipped with a high-flow 200 cell density metallic foil catalytic converter. We’ve found this to be the perfect cell density (CPSI) for performance and flow characteristics for the 2.0T K20C1 engine application. Compared to other options out there that use a 400 cell density catalytic converter, this downpipe will simply out-flow them all. Better flow = more power!

For all you FK8 owners, not only does our downpipe work extremely well with your OEM exhaust, it cranks out even more power when paired with the benefits of our larger and freer flowing 27WON full 3-inch cat-back exhaust.

When you purchase them together, you can save $92.71 dollars while having the sickest sounding exhaust on the planet and the only full turbo-back system on the market from a single brand.



Dive in to OEM design and it's limitations.

Added volume, reduced back-pressure, better turbo response.

Power! Tons of it.
