Has anyone taking there ss tc in that has engine mods like an DP? Would it be a good idea to throw stock stuff back on before i go? I have a check engine light probs from my catless dp, but now i am noticing a weird exhaust note n growing concerned about my engine

 

Why don't you put the stocker back on and see if it goes away?

 

yeah try putting the stock back on

 

scan your car b4 going in just to see what the code is but more than likely if u dont have a tune to ignore the code for no cat then thats what itl be
