The single oval resonator features two designs inside; an absorption resonator and expansion chamber resonator. These act to remove low and high frequencies and allow the exhaust gases to pass straight through.

The curly pipes on the side have a very specific task: to cancel out unwanted drone at specific engine RPM ranges. The two pipes each affect a specific RPM window; ~2900rpm and ~4000rpm. These points had excessive drone in the Type R that we wanted to get rid of. These side-branch resonators do not affect power or peak volume output. They only serve to cancel out specific unwanted frequencies that create that awful in-cabin drone.

Increased flow is always a key to enhancing the performance of your engine. We increased the exhaust piping diameter from 2inch up to 3inch (76mm) to increase maximum exhaust flow and power. This results in more than a 100% increase in cross-sectional area to support future power modifications.

What’s a performance exhaust without power? Over a 7 run average compared to the OEM exhaust, we saw a peak increase of 16wTq and 11wHp with a measurable gain over the majority of the power curve. We are confident we got all the power to be had from an FK8 exhaust system.

Every exhaust has connections and how these connections are made varies from basic leaky slip joints to the best option, v-band flanges. Every connection except to the downpipe utilizes a precision-machined v-band flange connection. Why?

V-bands give durable and reliable sealing with lightweight construction compared to thick bolted flanges. Additionally, there is no gasket to degrade or lose. This is just another way we

There are absolutely no compromises with the 27WON Performance Exhaust, not even the hardware and accessories. Every exhaust system comes with stainless steel t-bolt clamps and multi-layer SS gaskets where needed.

The Type R signature triple tip design was honored with the 27WON Performance Exhaust, but with a twist of REDEFINE. Instead of a smaller center tip, we opted to make the center tip the focal point with a diameter of 112mm (4.40inches) and a 100mm (3.90inches) tip to either side.

Adding a level of performance and sophistication, each tip is a polished 304SS dual-wall design that really complements your Civic Type R.

A critical design element we would not compromise on was the connection between the front-pipe and the remaining exhaust. The OE necks down to 50.5mm (2inches) here and many performance exhausts on the market do the same.

Our exhaust maintains a from the downpipe to the tips with our included frontpipe.

Every 27WON Exhaust System is crafted from T304 Stainless Steel that is CNC mandrel bent and precision TIG welded for a long lasting and durable performance part.

More power and more savings! Add even more power to the base cat-back exhaust when you bundle it together with our 27WON High Flow Downpipe specifically designed for the Type R. We're talking about gains you can feel on the street and on the track.

Ok, what about the savings part? When you purchase these parts together, you can save $92.71 while having the sickest sounding exhaust on the planet and the only full turbo-back system on the market from a single brand.

We understand that poor fitment and installation is frustrating, that’s why we have designed the 27WON Exhaust System to fit and install without issue AND does not require the modification of any OE parts.
