Some people may ask why I should purchase a performance or aftermarket muffler. The reason behind this may be that you would like to squeeze and extra 5-10 horsepower out of your car. Due to stringent emissions regulations and high cost of fuel some manufacturers have decided to make cars with restrictive mufflers. If you’ve decided you want to purchase or buy a sport performance muffler, there are many to choose from. However there are certain things you should look for when buying a performance muffler.
Features that a performance exhaust system should have:
2.0” – 3.5” diameter
· The larger the diameter of the performance exhausts system, the less restrictive it will become and thus give you lower end power and torque.
· Stainless steel performance mufflers or Aluminum mufflers are usually the best muffler.
· Mandrel Bending
