Hi,

On the website of novarossi I saw this about headers.

http://www.novarossi.com/eng/__news_5.htm

Does anyone know if this works on O/B modified NR's too?

Ronald. :unsure:
This is what I mean exactly:

Part 41015: 5 fins manifold - short type (best solution on long straights)

Part 41016: 6 fins manifold - medium type (suggested to have more push exiting curves and on the straight)

Part 41017: 7 fins manifold - long type (more power exiting curves)

Will these work for boat-engines too?

Ronald.
 
Call Bill @ the number listed on the website. He will gladly help.

Ronald,

It appears to me that they are essentially just spacers to allow the car guys to change their pipe lengths. The on-road car guys use different headers / couplers to what we use in marine applications and changing pipe lengths is not something they try as often as boaters......
