Straight forward

These diffusers look great. The fitment to the oem bumper is pretty good as well. Measurements the instructions had were alittle off, I measured twice to make sure I was correct but for the outboard diffusers it overlapped the bumper and it would have been impossible to install so I used my own measurements. They are simple to install, take your time with measurements and do it right the first time! Overall great product for the price and quality for them are great too.

Easy install. Great look.

Easy install, all I used for the install was masking taper or correct measurements and a drill to make some holes for the screws. feels securely bolted with all the included parts. Was hesitant to purchase this product due to lack of reviews but I’m happy I did. The price is very reasonable. Would recommend👍

Nice add on..

Seem to be very durable, they are cool in their construction, I didn’t see in the description that these were "sandwiched" in metal, was a surprise to me, but I like them, brought a sweet contrast to my Challenger....

Make sure to look for the item with camera hole

Product is great and easy to install. Only thing I don’t like is that it didn’t have camera hole. Other then that it’s great looking at a reasonable price.
