I've seen a lot of exhausts that say they fit 07-10 and then i've seen some that say they fit 07-11. Does this mean only some will fit the 07+ or all of them should fit 07+? Also I noticed some intakes say 07-10 but the Alta intake fits the 07-10 and the 2011+ according to they're website. So will all the intakes fit the 11+ also? Thanks!
