We see lots of newcomers onto these pages every day so please let this serve as a starting point for you and your mod journey.

This is super helpful. I'm not a noob but I still learned a fair amount.

Question: How much performance is there to be gained by installing a catless DP and full exhaust?

I know your target audience is for those with the 1.5 turbo, but all Civics aren’t GDI, as mentioned in your first point.
The 2.0 NA still uses port injection. Just throwing it out there for those who don’t know.

You mention the noise if GDI. Is the seemingly common “cold start rattle” something you guys at 27Won have experienced and is it something to do with GDI? I’ve heard of dealers telling people it is the high pressure fuel pump

my bad should have been more clear. There is still that NA multi-port. I can only assume that will be GDI in a few years.

Honestly, this sounds pretty normal. Like the dealer said it could be the pump. GDI is just plain noisy.

so the Facebook video linked didn't work for me, does the GDI sound like Valve Tick?
Other Questions,
How does the TPMS on this car work?
At what point in lowering do you have to invest in an aftermarket camber adjustment setup? Not that I can even lower my car with my driveway but just curious.

That's the FIRST thing I thought too. But figure it couldn't be since it's a brand new car. I can confirm that what I hear on my 1.5T sounds like valve tick. But if that is this GDI I don't know, as I'm not too familiar with GDI.

Figured something else out people may want to know, You know how this car doesn't do the courtesy lights thing when you unlock with the keyfob so you can see the car at night like every other car on the planet and just only has an adjustment for how long the lights stay on after you shut the car off, well if you have your headlights set in the AUTO position then you use Remote Start to crank the car then Unlock with the KeyFOB the headlights will come on with the unlock.
