ok ive heard that 2.25" exhausts are for top end and 2.5" for mid range.
n that 4-1 is top end and 4-2-1 is for mid range.
im thinkn of purchasing 'DC Sports Ceramic Race Header 4-1 JDM Style' and a jdm exhaust (fujitsubo power getter) but arnt JDM exhaust 2.5" so if i purchase these 2 mods..would it lag down bottom?
