help loss of power!!

I've just had a novitec middle and back box fitted with a new middle section section cat,
The car is a t reg 2.5 v6 156
It's sounding lovely but the power is lacking I'm worried that the cat is to restrictive should I go with a sport cat?
It's struggling to rev over 4000, but I can force it through, kinda hard describe
Any ideas?
