For an NA setup overpipe and catted high flow front pipe does minimal for gains except make your car louder.

THIS
Invidia N1 will be much worse
I have Gruppe-S UEL and overpipe (not sure why yours headers didn't come with the overpipe?)
Invidia Catted FP
HKS Legamax Premium catback
It sounds great no drone, only opens up when you put your foot into it and im a 37 year old who doesn't like loud ricy exhausts.
Also do you have a Tune??
An OFT with the v4.03 tune helped immensely with low end noises.
In general any of the Cannon N1 style exhausts are going to be louder than the suitcase style mufflers (stock style). Unless the cannon mufflers have an Helmholtz resonator somewhere in there.
