I want to build a new exhaust. What size do I "really" need?

Many of the 4 cylinder rice burners have faster times that 11's but did you ever think people are part of this forum because of the look, the feel, the sound of their maverick? don't care if you or a honda civic is faster than me. I like my mav. Everyone has different needs for exhaust, so don't think your way is the only way, and don't be a tool and get all butt hurt when people don't take your word as maverick bible.
