F.S. My Mynes V-2 Header, while having about 80,000 miles on it, it's in like new condition, no rust (of course, they are stainless), no dents, and barely a scratch on it. These headers already come with not only a factory o2 sensor bung, but an additional bung for a wideband AFR sensor. Price is $450 + shipping without the CAT or $600 + shipping with a OEM CAT bought new with the header.
