421 is better for more low-mid end where the 4-1 is more mid-high end.....picking one depends on your driving style
(Ive had both...currently a 421. I like the 4-1 better)

comptech isnt the best
Landscape Powercore adds close to 8whp and 3ft lbs...OC's has it, I think. (Dyno'd by 3rd party)
Comptech header for the ek adds 5whp (comptechusa dyno)

comptech is more than $100 more than the Powercore header
