Now that you did it what differences did you notice- sound, power, anything?

I see you got it over 800rwhp!
Haven't been on the forum as often, have to catch up!
Yes, I finally broke 800 at 107*F ambient temp...I'm looking forward to dynoing/racing on a sub 80* day. Maybe in October...

I didn't notice anything significant on the high flow cat to no cats mod. My primary reason for making the change was the concern of melting the cats at my current power and causing flow problems. Everyone I talked to said I needed to lose the cats at my power level. There may have been a slight increase in sound, but again not was loud before and still loud.
