What's the difference between the Base and Premium rear bumper?
The Premium bumper is a 2-piece unit with body color painted portions and some textured black plastic. The Base bumper is a single-piece unit. These Diffuser Fins were designed specifically for the Premium bumper, though many customers have successfully installed them on the Base bumper as well.
Will these interfere with my exhaust tips?
No, these diffuser fins are designed to mount between and around your factory exhaust tip locations. They will not interfere with stock or most aftermarket exhaust setups.
Can I install these myself or do I need a professional?
While professional installation is always recommended for optimal results, these diffuser fins can be installed at home with basic hand tools. The included L-brackets and hardware make for a straightforward bolt-on installation process.
