So i have athing where i have to mod my car atleast once a month or ill go nuts soo i think i'm gonna go with a downpipe. My friend said something about hogan but i haven't really heard anything about them, and i want something cheap for now. Also i was looking at zzp mps and on the chart i remember it saying a 3.5 is reccomended for totally stock 97-03 gtps but i kind of ignored it but i think i wanna do it if it's possible without blowing up my engine. Right now i just have a zzp pcm, slp catback system and a cai, So can i get that 3.5 without blowing up my engine cause of high kr or can i get it and just get colder plugs and a tstat and i should be ok on the kr ? I just wanna feed my mod addiction.
