RTR Rear Diffuser (18-23 GT; 19-23 EcoBoost w/ Active Exhaust)

Signature RTR Looks

I put this off for a while because I wasn't sure about cutting the oem diffuser. Once you get into it it really isn't bad at all. The cuts don't have to be perfect which aids a ton in the install process for people who may not be 100% comfortable doing this. Once it's over it looks immensely better, slightly bigger but more aggressive. It's subtle enough to not be over the top but still noticeable. The perfect upgrade to the s550 especially if you have the other RTR aero parts.

Aggressive

Definitely makes my rear valance stand out and look more aggressive

Awesome Diffuser

The diffuser itself was really simple to install if you follow the guides, used an air saw to cut the factory fins off and the brackets are self tappers into the diffuser so you will want to thread them in but not all the way. Great product!
