The thing is though, there won't be any significant or detrimental decrease in low-end torque. The Carrera intake isn't exactly a short runner manifold like you'd find aftermarket for a Honda or anything that would completely kill the low-end. It's just that the 930 manifold is so restrictive. Just remember, torque at higher rpm equals more hp, which gets more work done. Stump pulling torque at 2-3k rpm doesn't necessarily make your car faster if your hp/tq is practically plumetting off the face of the earth on the top-end.
