So I recently purchased a 2000 Honda Civic SiR. And after browsing some of it's features under the hood, I began to wonder if it had had a vast amount of performance enhancements done by one of the previous owners.

Here's a list of the parts it has which I think may be aftermarket, but I'm not sure. I would love it if someone could tell me if all, some, or none of these are stock.

DC Sports 4-2-1 Ceramic Headers

Front and Rear Strut bars

Cold Air Intake

Short Shift Kit

(Possible) Racing or Aftermarket Clutch (Seems very Precise)

Adjustable Coil Springs

There may be more, I'm finding new stuff each day. But if anyone could let me know what from this list, is aftermarket or not, I would greatly appreciate it.

Thanks in advance.

Everything sounds aftermarket except for the front strut tower brace. I believe that was standard on the SiR model.

The clutch could be aftermarket or OE. Honda manual transmissions are very good on feel and precision.

Cool, looks like I got the car for a steal then. Thanks a lot.
