thanks ironfist for the DIY. unfortunately i ran into trouble with that 4th bolt on the top of the header. didn't have a deep socket so the socket i used basically rounded the nut . long story short had to go to a mechanic i knew and he ended up screwing me over for money. quoted me an hour then charged 2 hours . so i payed $110CDN to install it . whatever i only paid $20 for the actual header. As for performance i noticed my rpms were high since this so called mechanic did not reset my ecu. after i did that. i noticed some small gains but still nothing earth shattering(i also had my silencer off). actually i had removed my silencer on my exhaust and i swear that gives me the best gains out of any mod so far. with my silencer i noticed my exhaust is quieter now and my whole powerband feels smoother. my rpms don't drop as fast. it's actually kinda weird because my car doesn't feel like it's pulling harder but by looking at my speedometer it "seems" to accelerate quicker. i know this is just a butt dyno and small observations on my part so take it for what it's worth. i know i don't believe much without a dyno either. Is it worth the money I paid for it? yes. Is it worth the money brand new? undecided as of this point. i'll have to see how the ecu adjusts over a couple of weeks and i'll keep everyone informed.
ive noticed that most people on here that have HP headers only get the top portion. i got the header that goes all the way to the undercarriage, where it then bolts up to the cat.
heres a pic incase you were wondering:
the pics on the first page... i notice on the stock header the little hole for the o2 sensor i think it is. in the hp header i didnt see it. or maybe i just missed it. does the hp header have that little hole?

anybody know how big the diameter of the actual piping is? from the innerside that is, not outside.
im in the market for a header but i dont know wheather i should go with dc 4-1 cermic or the hp cermic. i know the hp got biggers pipes, but with smaller pipes > higher pressure > low end. so if anyone can measure either the hp top portion header, and/or the dc cermic header... i'd appriceate it. 100 pts if u like =D
