So i installed a stage one kit a while ago in SRT and i was just wondering the benefits of it.
Some guys say that it eliminates a exhaust code so you dont need to install a catalytic
and you wont get a check engine light if you want to run a 3" turbo back???

Any info on the stage 1 kit would be great thanks

 

S1 will allow you to run a catless downpipe and will also let you run higher boost w/o throwing a code. Pretty much a less pickier version of the stock ECU
