You need the headers for the 14-bolt unibody head if those C8 heads are original to your car.
Other headers are very "iffy" on the fit since the flange isn't made specifically for the low-port unibody head. Some folks do okay with getting them to fit but most are plagued by exhaust leaks due to the port misalignment.
Now none of this means that it's smooth sailing. No matter whose headers you use, you'll swear that there's no way the headers were made for your car. A lift or some other method to get the car three to four feet in the air will help a lot. Be prepared to do some tweaking on the tubes. No, you will not have to cut the shock towers but that's about it.
Yes, ceramic coating is a great benefit unless you want to do this again in a couple or three years or so depending on what elements the tubes are subjected to.
Power increase depends on everything else about the engine. Ten to 15 horses on the small end. More horsepower if the engine has the ability to breath deep. |
