So I took a leap and tried something. I wasn't happy with the Weapon-R and DC Sport Header prices so I did a little research and found the 10th gen corolla/scion xd/toyota matrix headers should fit the 11th gen corolla. So I bought an ebay header and for $95 and it fits! No specific seller just the search term in the link below. https://www.ebay.com/sch/i.html?_fr...tleDesc=0&_osacat=0&_odkw=2012+corolla+header Here's the thread I got my info from to replace the header, great write up: http://www.toyotanation.com/forum/3...ll-headers-corolla-2zr-fe-engine-aircmry.html I had to take my bumper off to get on my rhino ramps so I started there first: Then you have to remove the wipers and that whole assembly: Then comes the fun part: Since the header is physically bigger the way the pipes are, its a tight fit getting it into the space but it works, just have to wiggle it around and play with it to get it in past the motor/windshield. Note, bolts aren't tightened yet in this photo.
