im lookin to get an exhaust and headers eventually
friend of mine told me if im guna do it, do it at the same timeee?
whyyyy

 

you'll be able to feel the gains alot more htan installing them a few months apart, and your exhaust is techincally only as good as its most restrctive component, so you wont see as big of gains with a catback on a stock manifold vs. a header

 

Also because they are connected toghether. so once you reach one, might as well replace the other one.
