A duckbill for a sedan definitely wouldn't fit properly on our cars without a lot of hacking. Good luck in the search.

Thats just a flap to add to the Si spoiler.

That looks like a pseudo McLaren airbrake attempt that will do nothing but impact fuel economy.

Any GOOD 10th gen SI coupe diffusers? I keep seeing pics of them but can’t find where to get them

My fuel economy tanked with it installed.. I took it off

I put a roof spoiler on and got about 3 mpg back... easily 38-40 mpg highway again which is plenty good enough for me.

Tbh I installed it and my MPG stayed about the same but I also tuned my car and FBO So for me to still get the same MPG with it on before I was tuned that probably means I would get a lil more if I didn't drive it like a bat out of hell . I get anywhere from 26 to 28 but I also do more street driving. I'm only on the highway for five to 10 minutes and my daily commute is only 15 minutes at a time so . If I were to cruise on the highway for 15 to 20 minutes straight, no traffic. I've seen 31 almost 32 MPG

I'm also not sure if some people have their fuel economy meter set to reset after every fill up/ ignition off/ or manually (which basically means never lol So it'll slowly go down every time you drive the car). I have mine set to ignition off so I know my economy per driving session

I’m getting 36-40 MPG, I have FBO also. And a Ktune. It caused it to drop down to around 28-30 on the highway I think. It was a year ago, so I took it off. My car is for fun but I bought it for fuel mileage.

36 to 40 . Damn lol... How many miles do you drive a day though. Cuz I only drive like 15 to 20 a day So I don't think I'm even traveling enough distance to get that kind of fuel economy. Especially considering again. I'm like 90% local street driving stop and go . I know it's more for looks though, especially considering the car is FWD. The car does feel more "planted" when I take sharp curves aggressively with it on though
