One of the best ways to gain performance out of an OEM turbocharged vehicle is to upgrade the exhaust system with larger and more free flowing components.

27WON 80mm Catted Performance Downpipe is a simple bolt on solution to help reduce back-pressure and increase both turbo spool and horsepower gains on your 1.5L turbo 11th gen Civic.

T-304 cast stainless flanges and a 200 cell converter are just some of the key aspects that make this the only downpipe you will want to consider for your 2022 Civic EX, Touring, and Si. Check out all the details below that went into the 27WON Performance Downpipe.


The inlet and outlet of the 27WON Performance downpipe are CAD designed for optimal flow, durability, and fitment. The industry leading 80mm bellmouth opening creates a large volume area for hot exhaust gases to escape quickly, providing increased turbocharger efficiency and response.

Keeping heat inside your exhaust pipes and away from other engine sensors and components is important for both your safety and that of the car. That is why our downpipe includes the provisions needed to reuse both OEM heat shields that come factory on your car. By keeping the heatshields we make sure max exhaust energy flows through your downpipe and not around it.

All downpipes are TIG welded using the latest welding techniques to ensure a trouble free system that won't leak and will last the lifetime of your vehicle.

Both ends of our downpipe use cast T304 Stainless Steel to allow us to create the shape we want. Our large and smooth openings give the ability to move lots of air to help backpressure and improve overall performance.

The 27WON downpipe comes equipped with a high-flow 200 cell metallic foil catalytic converter. This helps keep away any unwanted smells and cleans the exhaust gases exiting the vehicle.

Downpipe and Front Pipe

Great quality and good installation instruction. I would have given 5 star but there was missing hardware. No lower downpipe brackets so I had to bend and reshape oem brackets to fit new downpipe.

Awesome

I got the downpipe / frontpipe combo with the stock exhaust and it sounds really good. You get crackles and pops that aren't too loud, it's just really pleasant. I can go to work at 5 without bothering anybody. Pair it with a tune and it really shine.

I can't comment on the install process since I had someone do it because of the snow but it didn't look hard at all.

Really happy with the purchase!

Perfect sound + performance

This is probably the best power mod you can make after tuning the car, also has a ton of burbles and pops when lifting off the gas pedal. The high flow cat will be useful for adding power with both off the shelf tunes and custom tunes.
No issues during install, everything went smoothly.
I used a ktuner to disable the O2 sensor so I do not know if a check engine light would have came on or not.
