Here is some of the pictures of the 2.3 Quad 4 Custom Headers that are avaiable . These headers are stepped with a 4 into 1 collecters.They are made with 18 gauge tubing and a 3/8 flange. Can be made with 1 5/8 to 1 3/4 tube sizes or the big ones with 1 3/4 to 1 7/8 tubes. All collecters are 4 into 1 and 3 " with a 3 bolt flange. These headers are $450 plus shipping. The cost of tubing has gone up , but so far my welder has not charged me for the increase. Can have the headers Ceramic Coated for $80 if wanted. Any questions call PM here or email me at firstname.lastname@example.org
I belive that w41442 showed a 20hp increase on the dyno on one of his Calais's with just a header swap (and of course the exhaust was revamped to suit the header)...
This is definatly on my "to buy soon" list.
