Performance ok, installation NIGHTMARE
Ordered the set and some 1/8" thermal wrap. When I got them they were shipped fast and looked cool, the finish on the mating side looked a little crude but whatever. So, wrapping shorty headers is a horrible and tedious mistake, at least with 1/8" thickness....
Onto installation, I had a lift and easily unbolted the exhaust system and unplugged the O2 sensors easy all except the one at the top of the passenger side. I had to unscrew it from the pipe. Once I unbolted the starter and the steering rack (loosen rack bolts from the top, the nuts are welded in place) I started tackling the exhaust manifolds. The biggest pains are just ahead so keep reading.
Once you remove the bolts from the manifold and take off the manifolds you have to remove the studs... double nutting the studs and backing them out was very tedious and actually getting the new bolts in place was hours and hours of failure and exhaustion...
!!!IMPORANT!!! It would benefit your blood pressure to re-tap all the stud holes since mine were all sorts of warped out of shape. When the time came to put the heavy headers in, the bolts only wanted to cross-thread EVERY TIME I placed it. ALSO, the instructions SUCK... if you see the open cuts in the flange at the top rear of the header that's because you are supposed to put the bolts into the head before placing sliding the headers up into them. The instructions attempt to say this but the English is very poor, be sure to get all bolts started before tightening them down or you will cross-thread them. ALSO, you cannot remove the steering shaft, you have to push the steering rack foreward to get the steering shaft out of your way. ALSO, if you do wrap the headers you will need to remove the battery and battery box from the car or you will loose all hope for getting the rear most bolt tightened.
I also changed out the stock exhaust for pypes, sounds nice but I haven't seen any performance gains, Only fuel mileage... I need to get the car tuned, It's probably running lean and melting my cats.
