Hi im new here and new to injection but eager to learn! Just bought my first 5.0 mustang and its got alot of performance stuff but still has the smog pump as it was from cali but we dont have emissions here and im lookin to get as much power as i can........soooo i was wondering, i read else where, if i were to remove or by pass the smog pump then i would also need to remove the cats from the exhaust or they would clog up on me or what not?
