For me,using 3" isn`t a matter of money but performance.Dual 2.5" is more than just adequate for most motors.In fact,running 3" on something with less than an awesome motor can be too much and would run better with 2.5".You can run too much pipe.Depends on if you`re going for performance or just sound.I run 2.25" on my under 300hp trucks.Over 300 gets 2.5",and 3" goes on 450+ for my uses...
Get electric cut-outs if you really want to open it up!!Talk about turning heads.
My friend has a hot Firehawk.It looks factory,but has headers,gears,drag radials,cut-outs,and more.We`ll sit at a light next to a Mutwang,or whatever,open them up and rev it,then shut them up(unless they still want to race).It`s scary!!!
