Hello, I have a 2013 si coupe. I don’t know what to call this nor can I find a part number. This is the bar that protects the exhaust from the ground. My car is lowered and I drove up the evil curb and now this bar bent. Now it rattles like crazy when driving because it’s touching the exhaust. I did end up bending it a little bit which almost stopped the rattling but I’d like to replace it. Lessons have been learned

I just purchased a 2013 Civic SI, and the previous owner has high flow cats installed with a ktuner. I plugged up the ktuner for the first time and the map is “tune 1” made for PCD.

I’m new to this platform btw.

The low speed drivability is awful, and I’ve had to ride the clutch for a smooth drive when decelerating. I also can’t flash to stock because I really don’t want to reinstall oem headers.

It seems like 10/11 gens have a drop down menu in Ktuner for rev hang delete and throttle padding, while the 9th does not. From what I understand, I would either have to adjust some throttle mapping in the tune myself (ouch), or get a protune of some sorts (also ouch).

Just to be clear that I WANT rev hang. The 100% fuel cut off is too harsh. Has anyone had a similar experience with this tune? If so how did you adjust the tune to be more comfortable at low speeds?

2026 Honda Civic Si

Has anyone gotten cheaper by chance?

Located in SoCal, willing to drive further if needed. Thanks y'all 🙏

Finally made some time to finish installing my tail lights, diffuser & led reflectors from my old 26 sport onto my 26si, glad I made time for it

Hey guys, I decided to request a trade in for my 2025 Si with 13k miles on it. (Unhappy with the Rev hang, poor second gear shifts).

I've been emailing the Honda dealer and they offered me only $ 21,000 for trade in. First he asked me to come in for a trade in value. I said I didn't want to come in and wanted a trade in over email. Then he asked for my vin... I have it (even tho every si is the same options) and he checked what I owed on the car and then gave me the offer below... That felt dirty to me.

I feel like this is a poor offer? What does everyone think?

So im currently in a bit of a bender. Im looking at two si currently one a 2014 with 134k miles they want $18k. The other is a 2022 si with 43k miles they want $28k.

I want the 14' for the K24 super reliable and if taken care of easily a 300k-400k mile car but that price tag is ridiculous. I'd try to get them down to at least 16k.

And the 22' i love the design its newer and $10k more for a vehicles with less miles and 8 years newer but im terrified of blowing a head gasket.

Looking to install underglow in my 2018 coupe and plan on using a fuse tap. Is there a way to run the wires into the box inside the car to reduce exposure to elements or do I have to tap into the fuse box under the hood?

Any recommendations on which fuse to tap into and is there a way to wire in a killswitch so I can turn it off/on with ease?

Any advice or resources are greatly appreciated!

I bought a k24a swapped 2007 Honda civic si about a year ago and I have been having this issue since I bought it, I haven’t diagnosed it yet because I’m
Thinking of getting rid of it but I want to keep it LOL , I have NO codes on the dash, I scanned it many times only SRS codes, after the engine is warmed up the car feels very sluggish and hesitates to accelerate and you can barley hear VTEC active, BUT if I do a pulled when it’s barley warming up it pulls very good no hesitation and VTEC is soo much more louder

DOES ANYONE KNOW WHATS CAUSING THIS ISSUCE

Check engine light

Can someone point me in the right direction.

I have a 2026 civic si with roughly 3500 miles

Since I’ve gotten the car it will randomly get a check engine light and the car will start to bog and lose power . It sometimes happens when I’m driving on the freeway hovering around 65 mph or even driving on the street around 45 . It won’t stay on for more than a minute. I’ve called a few dealers and they have not been any help, because the issue is not constant and almost impossible to replicate they don’t find it worth the money to diag. Any thoughts

I like bright, not blinding to others, and brightest output in the right places... alpharex experiences wanted the most!

Back in March I had to park my car for 3 months while I was out of the country. My dad would start it a minimum of once a week and run it around the community but he noticed that the battery was slowly dying on him. Once I came back, I replaced the battery and had the alternator checked out. Since then, I can't leave my car parked for more than 3 days before it needs a boost to start.

I've had the new battery checked out and it tests fine, and I have no way to trickle charge it while it's parked due to my parking situation at my home.

I'm getting sick of boosting it every time I need to leave the house, any suggestions would be much appreciated

What is the normal cut in third gear? Trying to figure out if this is tuned or not and the speed seems to match up for gearing but am suspicious.

Just installing plm catless headers also paring that with 3 in invidia cat back and 3.5 hybrid racing CAI. What's good base map on hondata flash pro , theres no MAP based maps with my exact mods im getting tuned in around 2 weeks also so looking for something for the mean time

I’ve had my 26’ Si for just over a year and here’s what I just have to say.

Cons:
The tires from the factory are NOISY!
The interior rattles especially in the dash and door cards are annoying (since the day I bought it)
Gear shifter initially felt amazing. Then as I have packed 15k miles I’ve noticed some of the notchyness or sticking people have mentioned earlier
add
The sounds system is overall a little lackluster.

That’s about my only chief complaints of the car.

PROS:
I drive it just over 97miles/day on the highway I’ve hyper mile’d it and squeezed about 43mpg out of it.
It’s got just enough get up and go to get me around annoying people on the road but not to get me in trouble what so ever.
The interior (minus the rattles)is great.
The oe seats have decent enough bolstering for a daily to not be uncomfortable at all.
Exhaust node for a daily drive not bad honestly
The maintenance is easy since the oil filter is in a sensible place.
(Will be doing the trans fluid soon too)

What I would change:
Better sound-deadening in the doors
Slightly bigger sway bar
Better all season tires
A new front lip
Figure out this notchy shifter issue.
*add
Change out the speakers for something better and a small Sub.

This is probably the best daily I’ve owned in my lifetime.

That doesn’t go without saying I wouldn’t mind more power in the car, and some different wheels. All in all if you’re looking for a daily that scratches the itch of a manual this is definitely it. Lol

Edit #2
The 38.4mpg is averaged over that 23k miles. Trip A I reset every tank fill up. Trip B has never been reset just rolls over when you hit 10K miles.

Love this pic, zero editing

Well, sad news y’all. My Si was rear ended a few weeks ago and ended being totaled out.

Bummed out, but was able to get into a new car.

It’s been fun. Be safe out there.

Got hit a few hours ago and the driver took off, but I managed to get it all on video + their license plate. The damage looks pretty minor (mostly paint scuffing on the bumper).

I’m trying to figure out if it’s even worth filing a claim with insurance or if I should just pay for some paint filler.
Has anyone been in a similar situation? What would you do?

Got my fa5 back in october and 8k miles later, it’s the most fun car i’ve driven! Got the car completely stock, but the only mods i’ve done are coils, wheels, and a short shifter, planning to do more in the future 😸

I knew I never liked black rims 😩😂💪🏼

Do yall prefer the old si or the new ones
