I did custom exhaust for two years and what I learned about turbo mufflers, regardless of the manufacturer, is that on some vehicles they are very loud, and on others they are no louder than stock. Virtually every other style of muffler has an extremely predictable sound to them, you more often then not know how they're going to sound before you install them and therefor can recommend a muffler for the sound that the owner of the vehicle says they want. Turbos, you cannot predict. If you installed a set of full length headers (which I would highly recommend) the sound would more than likely change completely. They call them "turbo" mufflers because back in the day (60's?) when they started putting turbo chargers on cars from the factory (possibly the Corvair?), they quickly learned that the exhaust systems currently in use would not flow enough for a turbo car. Hence, the turbo muffler.
If you want something loud with a "period correct" sound, I would recommend glass packs. If you go to a reputable muffler shop, they can get glass packs of all different diameters and lengths. The longer the glass pack, the quieter the sound. If you do a glass pack with a smaller diameter, you'll get a more "raspy" sound which is what I prefer. I always put the shortest glass packs available to me on my vehicles by rule of thumb. The shop I went to last time I had an exhaust done had 13" glass packs on hand, but I think they said they could have ordered them in either 10 or 11 inches or something like that. Many people find it obnoxious but I think it's bad ass. Glass packs are a straight through design and they are not actually mufflers, they're resonators. If you keep your foot out of it they can have a decent drone that isn't too obnoxious, but when you hit the pedal on the right everyone in 3 counties knows about it.
The only thing I recommend straight pipe for are drag cars, diesels, and Harleys. I have a straight pipe on my diesel pickup and that's the only way to run a diesel IMO. My Buell has straight pipes too and it's obnoxiously elating. It will wake the dead. I had straight piped stacks on my 70 F-100 with a 302 and factory Mustang shorty headers. It was ridiculous and I loved it. It did rob torque though. The 351M's and 400's are so wheezy and there's no point in trying to modify them so you need all the torque you can get. Straight pipes won't help that, but it will love glass packs. I wouldn't go over 2.5 inches and 2.25 is fine for that. If you want to make power someday, get yourself an FE motor. 390,352, 428, 360, etc... Then get yourself some full length headers and a good intake at least. You won't believe the difference in power.
I very rarely got pulled over for loud exhaust, more my obnoxious driving. If you do things tastefully, it can go a long way. IE don't roll around in a loud turd, rather a loud, nice truck. I got PC-ed one night when I was 21ish because of my stacks. I started the truck after we had left the bar and I chucked a redine rev. With straight pipes and headers it made quite a racket. I wasn't driving yet and someone had taken a beer out to the truck, I don't remember who. The cop came over quite dramatically and asked "What the hell was going on?!?!" He said it sounded like someone had "Dropped a table off the roof". He gave me a ticket for an open container even though I hadn't left yet and I wasn't going to drive with a beer in the truck. My fault obviously.
Another time though, I got pulled over by a younger officer and he just wanted to look at my truck. He was pretty cool. For the amount of street racing I did in my FE equipped truck, I got away with a lot. I won a lot as well.
