For the 3L you should use a 2.5 inch single "quasidual" setup (Brullen & SCA setups are 2.5, Borla & Bassani are only 2.25) or 2" custom true duals. Remember the pipe from the cat to catback is 2.25 & will need to be upgraded (you could use a SHO-Shop Y instead of the MSDS Y & just weld in an extra support bracket but you will lose the MSDS warranty).
