| Description | The exhaust system for WRX STI / S4 owners seeking to extract even more performance from their car. The system is built around the muffler installed as standard on the limited edition STI S207, and has been tuned specifically for the base WRX STI. Back pressure is more than 40% lower to deliver much quicker engine response, which translates to noticeably faster acceleration from standstill or when powering out of low-speed corners. Featuring twin 101.6 mm diameter angled tips for a classy yet powerful looking rear, the entire system has been exclusively tuned by STI for optimum engine performance and reliability. Particular attention has been paid to the exhaust tone, which has been tuned to deliver a refined, soothing sound to suit the WRX STI / S4. |

Works well!
If you have Omni S1 pro this is everything you could ever need to maintenance for it! I have it run twice every night and you can’t beat $60 to have several repairs several times! Totally worth its money and fits exactly as if bought new!

Genuine parts that keep my S1 Pro running like new
Fit & Quality:
Everything fit perfectly on my Eufy Omni S1 Pro — the rollers snapped right in, and the filters matched the originals exactly. You can tell these are genuine Eufy parts, not knockoffs.
Performance:
After swapping the brushes and mop roller, my vacuum immediately started cleaning better again. Suction improved, and it picked up fine dust I hadn’t noticed before.
Ease of Use:
Installation took less than ten minutes. Everything comes sealed and labeled clearly, which makes it simple to replace parts without guessing.
Value:
It’s a little pricey compared to third-party kits, but the quality and compatibility are worth the extra few bucks.
Verdict:
Solid replacement set that restores performance to like-new.
