if i get pacesetters race-style what will i have 2 do on tune,so i dont get a light or a thrown code?

 

if you get race-style...which i would think means that the headers do not have hookups from AIR and EGR... you will have to remove the EGR and AIR systems since they will no longer have a need to be there.

you will get some codes for that..but it does not affect the performance of the car at all.. you will see the SES light on. you do not need to tune the car in order to get rid of that.. any shop with ls1 edit should be able to remove the codes for you for about 50-70 dollars.

tuning will make the performance of your car better after the header install though

 

you only have AIR and you'll need to have the codes turned off with edit/hptuner.

 

also will this smog? maybe ill throw on cats when i need em?
