Re: headers question
just like it sounds, the 4-1 is 4 pipes that merge into one, the 4-2-1 goes from 4, to 2, then to 1
wait, I'll go get pics
4-1 (all 4 merge into 1)
4-2-1 (notice the differences)
this is another example of a 4-1 header(shorty) but is a bit more rare
As far as power production goes, typically a long tube 4-1 is more focused top end gains, while a 4-2-1 will provide more mid range and slightly less top end gains.
4-1 are also known to have a bit worse ground clearance (as mentioned in the pic )
