I have the ZZP long tube catless DP and bung for O2/wideband. If I install this and bolt it to the stock catback will it throw a CEL? I assume it would because it will be a change in the flow and if it does throw a CEL could it cause potential engine damage?

 

yeah you will throw a code. because it is catless. it wont hurt anything though. just have the light on because the computer thinks your cats not working. which it isnt since there isnt one there.

 

it will throw a code. you can get it disabled though through your tuner.

 

Nice. I was thinking since I have an awesome 3 day weekend starting tomorrow lol. I may go install everything but the 2.7 pulley injectors and meth its all cooling mods so I wont need a tune really.
