I bought a high performance exhaust system with Flowmaster mufflers from Flanagan's Muffler Shop on Port Ave. I love it. It sounds great and I think I am getting better gas mileage. I know my performance feels better. The business has been around since 1961 or 1962, which made me feel confident if I have any problems. It is a family owned and operated business. I got a great price and I felt very comfortable with the staff. You can wait while you work is being done, but I preferred to drop my car off and pick it up later. They are open until 1:00 on Saturdays, but get there early because everyone knows this place is a good deal and they get busy. I highly recommend them. They also do converters, custom work, stacks, equipment, 18 wheelers, trailer hitches and electric work, plus a lot more. We have had several things done there over the years and have not had any problems. Check them out.
