Hfc

I didn't know they were defective until the install because the steering shaft would bang into the header every time I made a right turn. Luckily stillen was kind enough to honor the warranty and they sent me a another pair. But the labor of installing the header twice was just not worth the minimal HP gain they gave me.

I guess it pays to play.

I'm the original owner and it only has 17,000 miles on it (it's an 09). It has only been driven in the rain about 6 times and never in the snow or when the roads were salted. I purchased a long breaker bar, the correct sockets, PB Blaster and an O2 sensor wrench. I've also been told to NOT use an impact wrench. Thanks for the suggestion of using PB Blaster several days in advance. I've never heard of anyone referring to the bolts as "demon bolts" before. Im not exactly looking forward to the install, but i wasnt concerend about it. Should I be worried?

So far no CEL light just some smell coming into the cabin but its gone now. The car seems louder up front over 3000 rpm and a little deeper. maybe better throttle response too.
