Added a functional diffuser from ZL1addons. It’s the stealth version.
Install was easy once I bought longer screws for the two OEM mounting locations. The hardware zl1addons provided was good quality.
Took about 10 minutes to install once the car was on ramps and I had the correct hardware. Used shock proof thread locker on all 4 screws, and added a bit of extra reinforcement with 4 8” zip ties.
Provides a great seal with the muffler because of the included airdam. I was concerned about the material burning from being so close to the muffler, but nope, no problems all day. The diffuser held steady @ triple digit speeds.
Great product.
