Default High flow cats OR y-pipe?

What is the better bang for the buck mod?

and which one puts me more at risk of leaning out my AF?

Thanks!

high flow will lean you out but you'll still be ok.I have both i would say HF is best bang for the buck.

The CATS are arguably the most restrictive part of the exhaust system, so HF will net you the most gains.

Do the Cats or Kinetix resonated tests pipes. You FEEL a difference with the cats or test pipes. With the exhaust and Y pipe the car will sound better but the gain will be less. Best bet is to buy all three !
