Hey guys, I recently bought an Apexi N1 Single Catback exhaust, and yes it is a 3". I know I know, 3" is for turbo, but hopefully in the future I'll have turbo, I just wanted to put everything on only once. I know the piping is too big for a N/A car, but will the silencer help it out as far as back pressure? Obviously it'll be quieter but judging from the pictures it looks like it restricts the airflow coming out significantly. Will this help my back pressure/low end performance? Thanks all.

heres a link to what it looks like, scroll down:
