INSTALL DOES NOT REQUIRE BUMPER REMOVAL


Details

Here at Flow Designs we understand that Subaru enthusiasts love their exhaust modifications, which is why we've designed both, single (Option A) and dual exit rear diffusers (option B). The rear valance and diffuser fins will clear your Impreza WRX or Impreza RS G3 Hatch PFL single or dual exhaust tips with ease. 

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

The Impreza WRX/RS G3 Hatch PFL Flow-Lock rear diffuser shares the same durability and technology as our renowned Volkswagen Golf, i30N and Ford Focus RS line up which is trusted by car enthusiasts worldwide.

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.

10 year warranty applies for the rear valance (excludes ABS fins)

Great buy!
Size: Medium, Color: (001) Black / Black / White
My husband loves these. The socks are warm and thick and extremely comfortable. They support the foot and he works outside all day and has had them for a little over a month. They stay in place and don’t move move around while he’s outside moving around.
