^ with 447 at the crank you shouldn't have a hard time with bolt ons

I'm full bolt on my mods include PPE headers, Joe Z catback exhaust,Joe Z intake, RR Racing tune with their tuned intake system.
If that mustang is 447 crank hp with an average 15% powertrain Loss your looking at around 380 to the wheels roughly. ISF puts down between 350 and 360 wheel horsepower on average. Most in middle area 353, 354, 356 ctc.
I recommend going FBO but if you don't have the money for full bolt ons here's a quick easy way to create power this would require you to gut your primary cats that are attached to the headers. You will then have to install an O2 conditioner because you will throw a cell you can buy one from PPE engineering they are inexpensive. Last a high quality Cat-Back exhaust from Borla, Joe Z, Hayward&Scott, etc with hiflow cat, to help control the fumes AKA sulfur smell running with a gutted cat. That should put you in the high 390whp range maybe bit, more. You can go even cheaper still buy making your own exhaust running straight pipe, high flow cat and mufflers of your choice but can't guarantee what sort of power you would make.

As far as how loud the car will be that's up to you. It all depends on several factors whether you have headers, what exhaust you decide to use, they all sound different have different tones, different levels of loudness. Even having a high-flow race cat will change the sound level and tone for your exhaust. Also remember they all drone some louder than others. All these things factor into how loud your car is inside and out. I would classify my car's in the middle it's not extremely obnoxiously loud but it's not quiet either definitely a very nice deep mellow aggressive tone which is what I like. When I'm driving the car aggressively it sounds epic especially now with the inclusion of the new RR racing tuned intake, headers and cat back exhaust it's Symphony of noise lol.

I went with a 275/35/19R and 255/35/19F because of the poor road conditions where I live. It's a DD that I used to commute from Westchester County to New York City 5 days a week so I needed something with a little bit taller sidewall since I kept getting bubbles on my lower profile Tires. Here are some pics
