Looking for a header, I know not one part is the best and blah blah blah, but really which one sucks the least?
do a search or read the faq.
well, pacesetter seems to be a popular choice around here

Im a Xbox 360 fanboy...and damn proud of it!!
i got an obx header off of ebay at a good price and i noticed a nice power gain
Pacesetter is the most popular.
Pacesetter will yield more top end gains,
while the 4-2-1 OBX header would be more low-mid range gains in the power band.
If you go with Pacesetter get it Ceramic Coated.
