Weapon*R SW Intake System / Header / Header Back System + Dynos
DAMN!!! that is one beautiful header... very nice WR... yea i know what you mean by the space and install stuff... My DC race header for my Si barely fits from the bottom... i imagen the Fit could only be worst.
I stand/sit corrected. Heheee.

The header looks great. Might be the pics but the piping looks REALLY big.
I'm sorry... another question, Why do some race headers,( JR), tie together the first and third cylinder and then second and fourth cylinder, while other designs,( WR), tie together first and fourth and then second and third. I know that they should be tied together to equalize the exhaust "pulses" so that each cylinder's exhaust helps draw out the exhaust of the cylinder it is attached to, which logically would be first and third and then second and fourth,... no??? Any knowledgeable, factual info would be appreciated. Thank you.

Really want this header. The 4 into 2 and then one makes so much more sense then the shorty going 4 to 1 in such a short distance.
any dyno of just the header?
