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? |
