R1-Spec Catbackエキゾースト - ホンダ Civic Si FE1 [2022+]

The minimal bends in the design really let my Civic Si breathe on the highway — it’s aggressive but not obnoxious during daily driving. Install was straightforward, and the weight savings are noticeable in the back end.

The single exit muffler gives my Si a much cleaner look out back, and the sound is deep without being obnoxious on the highway. Weight savings are noticeable compared to the stock unit, and the minimal bends really let the turbo breathe.

Installed it this weekend and the single exit design really cleans up the rear end. The minimal bends make for a surprisingly smooth tone that’s noticeable but not obnoxious on the highway. Definitely wakes up the 1.5T without being too loud.
