Question about muffler delete and cai
So I have a muffler delete on my car and I really wanna get the Stillen long tube cai. However I know if you get a full new cbe that you would need a tune if you add a cai to that. What I don't know is, is if a muffler delete would be considered a big enough mod to make me need a tune with a cai installed... Should I just wait or would it be okay to get the cai now ?
