Initially ordered a fabspeed intake and then canceled after reading that a member got a cel. Eventually I'll go with bmc filters. I also came close to getting the ipd plenum but for $900 plus installation I didn't think it was worth it. Maybe in a couple of years I'll bite the bullet and get the x51 powerkit.

I have the evomsit stage 4 tune with fabspeed headers/200 cell cats with awe switchpath. I feel a difference In performance and after 1000 miles no cel.
