Thing is great!

Love it! Really starting to wake the car up with these new mods, install was very straight forward and 27won is good about being thorough with what to do (also providing pictures) during install. Only thing I would caution against; note that this does make the car LOUDER, my civic has a muffler/resonator delete and the car got extremely loud so I had to reinstall the resonator and its fine now but just a work of caution. Overall, awesome product thats quality made. Thank you 27won!

Waiting on some warmer weather to install so I'll update once complete. They did include 3 new nuts and bolts for the connection to the front pipe from the down pipe but none for the downpipe to turbo. I'll likely invest in the titanium stud kit for peace of mind since those bolts seem prone to breaking. Tracking and shipping were great as always.

Performance turbocharged engines love a free flowing exhaust and intake system.

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.

Precision TIG welding is utilized for the center section and the T304 SS heat shield brackets. The heat shield brackets are laser cut and formed with a multi-sided "foot" for a superior connection and durability.

Heat is the death of performance and durability. Designed to work with all the OEM heat shields our; down-pipe works best when paired with the benefits of our larger and more free flowing front-pipe. Purchase them together and save over $100.

The free flowing downpipe provides 7 wHP gains from 3200rpm to 5400rpm with no tuning changes. The 27WON Street-Catted setup provides great power gains. Throw some custom tuning at it and the downpipe really starts to shine.
