Thrush Turbo has a 'medium', slightly aggressive sound perfect for a dual exhaust V8 muscle car. I installed two of these in my old Chevy C20. I wanted to reduce the exhaust noise from the mufflers I installed, but I don't think it made much of a difference. So if you're looking for good sound then this isn't for you. Definitely a different sound than glass packaging. Scratchy sound. Buy them if you want your car to sound cool. Don't buy them if you want a quiet exhaust.
