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 considered headers, but the minimal gains and the amount of labor needed don't justify the cost. If I ever decided to do them, I would have them professionally installed.

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?

If you search for "demon bolts" on here you'll find mention of it -- the nickname is apt...

It sounds like you have all the tools you need -- it's just really tough to get them to break loose.

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.:driving:

You might be okay then -- the CEL is much more of a likely problem with TP's. If not, picking up some extenders should work.

Wow..I though I took long. It took me about 6 hours to install my Berks but I love them.The two front demon bolts were the most difficult but I sprayed blaster lub let the car run for 30min and those bastard bolts loosen up with no stripped bolts. Patience is key but well worth it..sounds like a mini GTR lol

I had a shop do my test pipes, for this very reason, and I'm told they didn't have any issues. BUT in the process the vibration killed one of the front sensors that I had to deal with myself. 50k miles and there was no way it was coming out without destroying some s**t. We even soaked it in acetone and ATF prior to touching it.

Here's the result. Had to re-tap the header while in the car. Never again...
