ok i've decided that my next mod will be an exhaust. should i go with 2.25 in or 2.5 in? for now i plan on gettin headers, flex pipe, cat, all the other good bolt-ons, a tune, cams, udp, and one day start building the internals. wouldn't a 2.25 exhaust be too restrictive?

i've been told 2.25 will only be good for mild engine mods. what you got set up, i'd go with the 2.5"
