What are the Advantages and Disadvantages of Using a Glass Pack?

How to Choose the Best Glass Pack Muffler?

Find out whether it is a single or a dual system. It will help you to decide the number of inlets you need in your muffler. A single exhaust needs a single muffler, and a dual exhaust will need a dual inlet muffler. Find the diameter of your exhaust pipe. For this, you have to compare your inlet and outlet with the present exhaust diameter.
  • Find the room needed for the glass pack – The outer side dimension of your muffler should provide proper clearance below the vehicle. Choose the correct length for quick installation and proper clamping. To fit properly within your vehicle, you must choose the right casing size and shape.
  • Pick up a style you need – There are three main styles available: chambered, glass pack and turbo. Chamber mufflers are suitable for muscle cars. They reduce noise by providing throaty performance. Glass pack mufflers are designed to provide horsepower and maximum flow. They are straight, and the perforated pipe is wrapped in fiberglass packing. They are a popular choice for racing cars. Turbo mufflers have S design allowing the gas to travel through the tubing. They offer better noise reduction. They are good to be used for street applications.
