Vibrant muffler model 1145 enough back pressure?
I have decided this model is the best looking without being shiny.
I don't care for anyone's negative opinion. Seriously I know people have preferences. But this one is mine.
I Have read that there are some mufflers are too free flowing and do not have enough back pressure creating a horrible sound. I also read that there are some that actually are mean for more top end. That means the actual usable power is not realistic under normal conditions. This will be used for a daily driver not the track. I don't intend to be redlining each time I shift. I want streetable useable power.
Can anyone give me more help if what I have read is correct and if so or not please explain.
Thanks in advance.

Less backpressure won't reduce power, anywhere in the rev band. You actually do want as little backpressure as possible.
The idea of needing backpressures come from putting headers with huge collectors and large diameter pipes on an engine, and due to the radical decrease in exhaust velocity, the engine ends up with less low/mid range power.
People thought it was the reduction in backpressure causing the results. It was the reduction in speed. Ideally, the lowest backpressure and the highest velocity is best, but it is difficult to achieve both.
You'll be fine in regards to performance, assuming you won't be changing all exhaust piping to an overly large size.
I can't comment on sound of that exact muffler. I can say that as long as you have a cat, and a resonator, then the muffler will only be needed to quiet things down, which that should do (seems like a typical straight through muffler with plenty of absorption material). It's when a "test pipe" is used and the resonator skipped that the horrible rasp tends to develop. The cat and resonator both act as expansion chambers, which helps prevent the resonance that develops in long sections of pipe.
