Moto man, have you looked into a Flowmaster exhaust? They sell a dual system at a pretty good price. Take a look at
www.flowmastermufflers.com and you can listen to the system they have for the PT. It sounds great. I have a single outlet Flowmaster system, and it has a nice low rumble at idle, and a good hum till about 3800 RPM and then it's almost like the exhaust cuts off and that cool intake noise picks up. I paid about $140 for my set up, installed. Definately take a look at Flowmaster if you want a good sound that has a good reputation. It doesn't have that super ricer "bees in a coffee can" sound.
