Does this offer any horsepower gains? Does it make problems with not having enough back pressure?

I sort of regret putting an exhaust on my car. Just because the ride quality was incredible without it.

Anyway, I thought it was pretty interesting.

Thanks.

Pressurized engines aren't effected by back pressure, the blower creates it's own pressure.

I've heard about this particular one having problems , that is if it's the electric one. Just put a manual one in just after the exhaust makes a turn after the resonator. my friend did this on his and he just reaches down near the front of the right rear tire and un-corks it with 2-3 wing nuts.
