opinions on headers?

[amikk97]

Due to a crack in my manifold im looking to replace them with a set of headers. however, im still running a catalytic converter, will headers still work with one? i still have to go through emissions and stuff so i cant remove it yet but i need to get the manifold replaced asap. im currently looking to get these: http://www.summitracing.com/parts/sum-g9006/overview/
they seem to have good reviews and im on a tight budget so im thinking about pulling the trigger on these when i get my next paycheck. what do you guys think? is it worth it? or should i just get a new manifold?
