Nuss, I just put the primary cats on my car, no secondary cats, no muffler and way too loud. You may want to start with muffler delete and secondary delete and see if that works for you first.

I have already done that,,then I saw your post, my left ear hurts now after driving the car,, i think I will wait to hear a video of yours before I make the final decision. Mine sound really good now, just wanted to get the F1 sound... looking forward to hearing yours.. Thanks Nuss

The bypass pipe poses no problem and no check engine light .
