This diffuser made such a dramatic change to the rear. It’s not too much, and not too little. It’s literally perfect. If you are looking to upgrade your NON-SPORT 10th gen civic hatchback, this is the best diffuser to go with! The diffuser was also fairly easy to install. Would recommend installing with 2 people.

I installed this myself pretty self explanatory but if I had another person to hold it for me it would’ve been easier but the fitment is perfect. Has a aggressive look and overall I love it. Would definitely recommend for non sport owners!

It took 6 weeks to receive the defuser, I installed it myself, I kept the rear mud flaps, i had to cut a split in the flap with a cut off wheel. The fit was perfect, had no problems. Well worth the $$$. I would definitely recommend them.
S
Overall it is rly nice and makes the car look a lot more aggressive. Pretty self explanatory for installing it. You do have to remove the oem mud guards and can’t put them back on. Only con is for me at least I had to drill a hole for the 2 side pieces for the black screws. There are no holes for it to go but it all worked out. I have a 21 civic hatch

Super easy to install although it didn’t come with any directions it was self explanatory. But I love it and it makes my EXL look nice! Can’t wait to purchase the rest of the kit.

I was hesitant to buy this as I live in NYC and when parking in city parking lots, you're almost always going to skid on the way in/out. I was skidding this no diffuser and I knew I'd skid with this.. LUCKILY, this has held up incredibly! Another reviewer shared the same experience and I am so glad I pulled the trigger and bought this. Months later - no issues. 5 Stars for a phenomenal product and 10 Stars to its durability!
