that's one of the key factors that led me eventually to the HKS Sport. It really does help preserve what little the NA has. I would bet that it's down 3-4 HP on the dyno from the Borla, but to me that's immaterial at this point. The car is much more enjoyable to drive around town. One thing you could do is try out 2" piping from your cats to the Hyper mufflers. You'd still have the free-flowing mufflers, but improve the low-end situation a bit. But, after all the experimenting I did, I'm not sure I could recommend messing too much with what you've got!
