guy i need some quick opinions on the greddy headers, if yuo have any sites to post with dyno charts or specs that would be great too, hekp me out!!!!
Thanks

 

I had one on my b18 sol..I liked it for the week i had it. good top end.

 

I bought a used one off of eBay for like $150. It had a small ding on the underside, but otherwise good condition. It's ok, I did notice some gain in midrange and top end, but pretty minimal since I only had intake and exhaust. For $150 it wasn't a bad deal, but I'll get rid of it as soon as I have enough for the JDM 4-1, carsound cat, etc. It's ok, but not great. I guess it's comprable to those DC headers everyone has.
