So after getting some inspiration from the forum, I've decided to have a set of Flowmaster 40 Series mufflers installed on Black Betty. I ordered from Streetside Auto for around 165 for both with free shipping on Thursday morning. One of the mufflers got here Friday morning while the others coming on Tuesday. Should have them both installed by Saturday afternoon. I will post up a vid once they are installed. This week is going to drag waiting to get the mufflers on lol.
