The inlet and outlet of the 27WON Performance downpipe are CAD designed for optimal flow, durability, and fitment. The market leading 3.125” downpipe inlet creates a large volume for the hot exhaust gases to escape, providing increased turbocharger efficiency and response.

Inlet and outlet flanges are manufactured from investment cast T304 stainless steel. Stainless steel piping and brackets are precision TIG welded for a long lasting and durable performance downpipe.

Initially purchased the catback for the Si Coupe and then made the jump for the front pipe and downpipe. The downpipe definitely adds a bit more sound, but zero drone. Fitment was perfect as with all the 27won products. Nice performance gain, especially when paired with the W1 turbo.
I can't stress enough how amazing this product is! Right away on a comparison to oem you can tell 27won focused not only on performance but quality. Install was real easy following the step by step install instructions. Pairing this with the W2, intake, race maf, and turbo inlet my CivicX launches on demand no questions asked. I highly recommend this product if you want to maximize your performance!
I installed the turbo inlet pipe a month prior to installing the down pipe. I was able to install the down pipe without removing the inlet pipe by taking out the bottom. I couldn’t be happier with this DP. It was the last piece of my intake and exhaust upgrades and it honestly woke this car right up. High quality part to e expected from 27WON.
I did the front pipe and down pipe at the same time. Not that simple of an install but the directions on the app help big time. I sat with an iPad next to me during the install and did this in my garage with simple tools. Fitment was great and noticeable hp gains after first drive. Quality pieces from the flanges to the finishes. Do yourself a favor and just order the fp dp combo and thank me later.
Got the High Flow CAT and front pipe, In love with it! fitment was perfect! Car is noticeable louder paired with my aftermarket catback exhaust
Installed as a full system. I could immediately tell a difference in sound and flow resulting in a little more power and urgency. This is not an easy install but I’d you just go one step at a time and follow the wonderfully detailed instructions you’ll get it done.
I recently installed my 27WON Downpipe an I love it. My Civic SI feels and sounds way better also the installation was a simple a process thanks to the instructions provided.
Amazing!! Front the packaging to the design to the performance, just amazing. This paired with the front pipe completely changed the personality of my si. Highly recommend this product.
This is a very nice downpipe, fitment is spot on and had no issues with the install. Install instructions are very detailed. Need pics check on civicx forums. MeanGreenSi, lots of pics.
