I'm sure others will chime in, Johns TI is top notch. Your car will never be the same. Great unit and great service. As for the o/r H pipe, your car will sound more throaty. If you do them together, ask John to turn off your o2 sensors as you will lose 2 of them when going with no cats. If he can't, I recommend Brenspeed for purchasing a tune.
