From spoon-sports.com:

Spoon's 4-2-1 Header utilizes a Tri-Y collector design to increase mid to high range horsepower and torque while minimizing the loss of low end power. Extensive Dyno testing results in a 10hp gain on B18C5 engines. The header is also extremely lightweight (6.9Kg as opposed to the 11.5Kg STD weight)
For use with the B16A and B18C engines.

Is this spoon header interchangeable with all B series motors?

If it is, are any of you interested in buying one, or trading a mugen 4-1 for it?

Thanks,
Demian

Yes its the same for the B16A/B16B/B18C/B18C5, Why do you want to trade one for a Mugen though? The Spoon is a newer Better design.

 

Because I'm singing the song "Which one doesnt belong?"

Are we talking a huge difference in power? more than 2 or 3 HP?
