The rear valance and diffuser fins will clear the FK4/FK7 Civic RS double exhaust tips with ease, and rear bumper removal is not necessary for installation of the diffuser.

The Flow-Lock interlocking system allows for the final assembly of the diffuser fins without tools or fasteners. A simple push and click and the kit is assembled and ready for installation - this means zero exposed hardware giving you the cleanest look for your FK4/FK7 Civic RS rear.

No more L-brackets, no additional exposed hardware and no double-sided tape, experience the Flow-Lock difference today!

Valance is installed to the car through bolts and nuts while the Flow-Lock diffuser fins simply click into the valance (once locked into the valance it is secure). It is also possible to install when your car is on the ground.
