Hey guys. The other day I got a SS sho shop y -pipe installed just 2 days after the mystery mod. Well my car is loud.. The mystery mod did a great job of giving me more modrange power. Then I got teh y-pipe (catless) and my car sounds deeper and feels better 0-60. I dont know about the y-pipe giving me higher end power 100> but it does a help. With an intake, pre-cats gone, Sho shop y-pipe, main cat gone and 2 mufflers....Do you think my car could use the SAFC? Would I be rich or lean?
Also has anyone done the mystery mod and not gotten a CEL?
Thanks,
joe
ps. For somereason I hear a turbo sound (whoosh) when I hit 3-5 k.I dont know if its coming from my exhuast or my intake? I dont think its a leak becuase wouldnt it make a really loud rasp for the air that doesnt get (baffled).
Anyideas?
