Default NA exhuast upgrade

Hey guys,

i know from researching our forums that the general consensus for a NA is to get 2.5 mandrel bent piping out back but i was wondering does the tip diameter going to matter. For example a 3inch dual outlet? Also on the CA models the car comes equiped with the 3 way cat system, which is restrictive right? Is it best to remove them and put a single cat on, since emission is required in cali?

well i dont see why you cant go 3in but as far as cali emissions go. you might have to put dual catalytic converters...if you got ppl go straight pipe, you get the most power that way
