Car feels faster with cutout closed?

well i already had a Lid,Cutout,Catback,Free Mods,and a diablo tune and i just recently added pacesetter LT's. i had the cutout open after the install and noticed a nice SOTP diffrence in the higher rpms, but my neighbors complain about the car being to loud in the morning so i put the cap on for a little and i notice the car feels all around faster for some reason????

I felt that way too, but did one run at the track open, one closed, and the difference wasnt barely noticeable. This was stock headers at the time btw.

Could it be because you was losing too much back pressure with the cutout open?

its quite possible I feel that I may of lost a tiny bit of torque off the bottom with just some very free flowing exhaust. I did LT & ORY and still had my stock catback and it felt a little peppier then it does now with the Corsa Catback...

I don't intend on putting a cut-out on my car until I do heads/cam
