I agree with this and also want to say that my '18 needed an alignment at it's first maintenance service. It was just outside of spec a year and ~5k miles after purchase. The roads where I was the first few months of ownership were rough.
I read about something interesting regarding these epa lawsuits. In another forum a user was having an issue with their aftermarket downpipe causing codes. Turned out that his downpipe was cracked along a poor weld next to the cat and, upon removal, it broke in two. He contacted the manufacturer...
Oh cool. You were able to get a turbo solution done? I remember you had asked in one of your threads. Were you able to get in contact with the thread creator I linked back then or did you piece something together yourself? Would love to hear about it, we need more people attempting these things.
Take a look at your state's dmv website and find your county. It looks like a lot of counties have an anti-tampering inspection, so they'll look for the cat and fail you if they don't see it.
Switching to 18's is a very common thing I've seen. I don't want to break a CivicX rule by linking anything, but a search for a related forum will lead you to a wheel and tire section that has people's experiences in what widths and offsets work well. For reference, the factory 19's are 19x8...
I'm 99% sure it is a new spam account. This is what they do. Generic response to a dead thread or 2. Sometimes they comeback and edit in a small link somewhere in the posts. Typically happens in the off-topic section.
Wheels and sticky tires would be my choice since you already have a muffler delete. Unless you don't like the muffler delete anymore, then I'd understand wanting to switch it up.
I had 11,200 miles when I sold my 2018 in October. I wouldn't sell unless you want to shop new, know exactly what you're looking for, and know you can get it without a mark up. The used market is a complete dumpster fire.
You'll need/want to get a custom tune. If there's nobody local you trust, you could contact Drob at IMW or John Vega at Phearable and see if they'll do an etune.
It's $3.53 a gallon for 93 here. It's up about 30 cents from this time last year. The year before that it was below $3.
*Prices are from the same station.
There's only 1 person I know of who did it. This is a link to his thread that was locked. He made another as an update later on. You'll have to contact him somehow if you are determined to do this.
