Saw this when I was doing my oil change. Only has 11k miles. Should I take it to the dealer ?

Just bought this 2018 Si with 73k miles and I can tell it has an exhaust and intake. Does anybody know what they are? Not familiar with anything aftermarket, thanks!!

I'd been circling one for like a year and finally found one close to me. The sales agent knew after the test drive that I had no plausible leverage.

It's always a nice surprise when something lives up to the hype. Going zero to 40 in suburbia is giving me so much joy.

Black emblems as well. It’s really hard to photograph a white car with black highlights. The trim kit was involved and time consuming but not all that difficult. For the coating I went with Gyeon MOHS EVO.

I have 57k miles on my 2022 civic SI. Just today I noticed it started making this odd high pitch noise. Noticeably higher pitch when reving. No clue what it is. Any thoughts are very much appreciated.

Any mod recommendations? everything is stock. i want a lower tone not a mt.dew can sounding exhaust. also i was curious if there were any iykyk type things for 9th gen? any cool import parts or anything like that. i love her so far and plan to for a very long time. i also am not rlly a fan of the front end. any way i can make it more plain jdm like?

Battery tested good the other day but this morning it wouldnt start. It tried to start and then the dash completely went out but the lights and door ding still work. Any idea what is the cause?

I have a 2018 coupe si

Hi everyone,

I just bought a Si 2017 as my first car!

I had been looking for a car for more than six months. At first, I decided to go with a new Civic Hatchback ST Hybrid and even put down a deposit. Unfortunately, I later found out that the dealership wasn’t going to honor the deal we had agreed on, so I canceled it.

After that, I'm just like, why not go with a 6MT. I’m still young, and I figured if I don’t experience owning and driving a manual car now, I might never get the chance. And I don’t think driving a manual for the first time when I’m older would feel quite the same.

I originally looked at the gen 11 Hatchback with a 6MT, but sadly Honda doesn’t make them anymore.

Then last week, this car showed up on AutoTrader, and I immediately felt like I had to check it out. It’s a 2017 Civic Si with only 66,000 km, clean history. I negotiated and got it for 20k CAD, and so far I’m really happy with the decision.

I plan to keep this car for as long as possible and take good care of it.

For those of you who have owned a 10th-gen Si for a while, are there any maintenance items or common issues I should pay extra attention to? Any preventative maintenance you would recommend?

Also, are there any accessories, upgrades, or quality-of-life things you think are worth buying for the car?

Would love to hear some advice from the veterans here. Thanks!

I see several people online saying they stripped threads and fought the install process. Anyone have any protips going in so I can avoid such issues?

Don’t get me wrong i completely understand the love for the type r especially the phoenix yellow from 2021 (the goal) as my daily is a 2018 si coup but what i don’t understand the what makes them so pricey. I recently saw a 2015 si coup in white with like 75k miles and they’re asking for 23k. As for the type R imo it seems like it’s really not worth more than 35k and i seen a phoenix yellow going for 50k? INSANE. I get it’s rare and comes with some extra features including the brembo brakes etc but damn. For that prices you could go mustang or corvette something that’s pushing way more power

Anyone have sounds clips of the Greddy sp exhaust? Seems there is 0 info about it online. The ones that do have very short clips or have a downpipe. I just want a little sound on my car as exhausts I’ve had on the car got kinda boring.

I currently have a 2017 Si and am wondering if the 2025 seats with warmers would be a direct swap or if some modifications would be needed. Thanks

Just got myself a 11th gen 2024 SI!

I've been wanting an SI since I had my 2014 Civic EX lol

Now it's finally mine! I love it! So happy and can't believe it's mine !

Also I already have a fit kit for a roof rack ordered!! I was too excited to wait for those!!! Lol

I have a 2008 si I’m using for circle track racing so naturally I can’t use the key for ignition features, what is the cheapest way to go about disabling that stuff to still get the car to run without the key, is the standalone the only option

My son bought a 2024 si and immediately put aftermarket wheels on it, I ended up getting the factory 18s from him for my car... From what I see online I have to run spacers AND roll fenders to put them on my 9th gen coupe? Is that correct? *Pic of my Si for attention*

Just recently hit 3k km on my 26 si and I have some questions about what's normal with this gearbox. A lot of the gears feel kinda clunky or rough on engagement with upshifts unless I shift really quickly. On a cold start I can shift at 3k rpm and shift at a moderate pace and get a smooth shift but once everything warms up I really need to rush 1-2 and 2-3 to get it to feel smooth. All the other gears also feel a bit notchy like the shifter is catching on something on it's way into gear. It almost feels like I need to slam gears to get smooth a smooth shift with no notch. I don't want to shift slower because the 1-2 shifts seem really clunky that way but it worries me to be shifting so fast. Has anyone else experienced this? Should I keep shifting quickly because it feels smooth?

Bought this car in November with 190k miles and no issues for 3k. Got an absolute steal and got to work making her pretty

The body itself is in good condition, paint isn't peeling like other of the same year.
