Any way, I have put a fart exhaust on the back

Any ways, its like 1.5 inch down the moddle

If i was to get 20v 4a-ge headers plus the exhaust and put my "fart exhaust" on, will i notice an increase in tourqe or loudness of my exhaust?
Hopefully this all makes sense, and i posted in the correct area, im new hear

Cheers guys
