Ordered a set of Kooks with cats, and a Peak Ported TB and ported intake,

Has anyone done these mods and,,, do they set off a code?

I will get a tune after the install but I don't want the car down for weeks, I will likely get a mail order tune to hold me over until the local tuner can get me in.

 

Headers, even w/cats will set a code for the 2nd O2 Sensor. The car will still run fine but you will have a CEL.

 

Cool, thanks, I will ship the ecu out for a mail order tune, then dyno tune it once the local tuner can get me in.
