Surprised it would sound like crap just from removing the cats which act like resonators. I'd think with plenty of other resonator/muffler in the exhaust to smooth out the tone, it would only be louder.

My guess is it was the notorious hiss on decel that the VQ is known for when you're running TP's or LTH's. I'm running LTH's and I have to say the hiss is a more pronounced than I thought it would be.
