I was going to get one next week, which is better: 4-2-1 0r 4-1? Ceramic or stainless? Thanks.

 

4-1!!!!! The "mid range" torque improvement has not been showing up on hondas.

Plus, mid range is 3000-5000. How often when wanting power do you drive in that range?

Search for "the great header test" to pick the best 4-1.

 

jdm 4-1

 

Basically the difference is that the 4-2-1 will make a power gain over the whole rpm range, while the 4-1 will make more power but only in the upper rpm range. This is according to DCS. Also as far as ceramic or stainless, stainless will never rust, ceramic will eventually rust, how much do you want to spend?
