DC Sports 4-1 Header, for the b16a(2). Brand spanking new, it's been out of the box (which I no longer have) but has never been installed and stored inside away from the weather. Asking $270 + shipping. DOES NOT include the O2 sensor shown in picture (I was making sure it fit properly) Megan Racing H brace, for the 2000 Si (it'd most likely fit any 96-00 coupe) Also new, and never been used. I still have the box it was shipped in. Asking $70 + shipping. No pictures but, I also have a stock B16a throttle body and a stock B16a fuel rail. 40 shipped for each and their yours!
