hey guys i just installed aset of asm headers on my 6.0 and of course the exaust is no where close to lining up so i was thinking instead of having the exaust shop piecing the exaust back together i would just have a new custom exaust put on.the question is if i take the cats off and buy the o2 sims will the ses light be on? i dont have ls1edit so i cant turn the back o2s off my computer was tuned by westers garage. is it really worth it to take the cats off?
