hey guys i have a 01 sh and i have aem cai,dc headers,geddy evo 2 cat back, random tech high flow cat, aem pulleys. i was wondering if i should do a 2.5 collector on my dc header or i should get top of the line header money isn't a issue for me just want the best gains out of a header for me. if i get something else that is better is it worth the money?
