How to Shop for the Best Exhaust System

Performance Exhaust vs. Factory Exhaust

  • The mufflers used in your factory exhaust system are designed to provide quiet operation by sacrificing some exhaust flow. High performance exhaust systems on the other hand, use mufflers with less flow-restricting chambers and baffles in them
  • Performance exhaust systems use mandrel bent tubing. This eliminates the restrictive bends commonly found in OEM exhaust systems by mechanically forcing the tubing to retain its round profile around bends. This results in greatly improved exhaust flow
  • By using mandrel bent tubing and free flowing mufflers, performance exhaust systems increase horsepower, torque and if you can resist using the extra power, fuel economy
  • If you want your ride to have a powerful tone, a performance exhaust system is the best way to get it. That’s because unlike your near-silent OEM mufflers, the mufflers that come in performance exhaust systems are generally engineered to produce a race-inspired rumble

Things to consider when shopping for Exhaust Systems

  • Start by determining how much of your system you want to swap out. In many cases, you’ll be able to choose from header/manifold back, cat back (DPF back if you have a diesel), or axle back systems. Generally, the more OEM tubing you replace in favor of free-flowing mandrel bent tubing, the more performance you’ll get out of your exhaust system. But depending on the ride, installing a header-back system can be labor intensive or simply impossible. In those cases, an axle back system will replace the easiest parts of your OEM exhaust to access, will add nearly as much power as a cat-back system and will sound far better than your stock exhaust
  • If you live in a dry area of the country, the aluminized tubing that comes standard with most exhaust systems will work just fine. But if you live in areas with high moisture and where road salt is used, you definitely need a stainless steel performance exhaust system. Now keep in mind not all stainless steels are created equal. Many exhaust system are made from T409 stainless steel, which is fairly corrosion resistant. But if you often find yourself cruising behind a salt spreader or backing your rig into the bay when lowering your boat into the water, you should steer towards exhaust systems that are made from T304 stainless steel instead
  • While some drivers crave the loudest, most obnoxious exhaust systems, the constant droning they sometimes produce can become annoying if you commute long distances with your ride. So for that reason it’s important to gauge how loud a particular performance exhaust system might be once installed on your ride. Thankfully, we have tons of sound clips you can listen to and customer reviews you can read, so you’ll get a good idea of what you’re getting into
  • For the most part, our performance exhaust systems bolt on with no modifications required. But on rare occasions you’ll come across a kit that requires some minor welding to install it, which will be noted on the product description. If you want an easy installation, you definitely want to go with a bolt-on kit
  • We often get questions from customers who ask “Do you have CARB legal cat back exhaust systems”. The short answer is yes. You see, as a cat-back or axle-back exhaust system bolts on after your vehicle’s emissions equipment, it’s considered exempt from emissions inspections. The only time you’ll have an issue with smog checking with a performance exhaust system with a manifold/header-back system, or in the case or diesels specifically, a DPF-delete system. The reason is because these kits directly affect the operation and layout of your OEM emissions equipment. Also keep in mind emissions laws will vary depending on which state you live in, so when in doubt, check your local emissions regulations before ordering a kit
  • If you’re worried about the dealership voiding your car’s warranty because you installed a performance exhaust system, you have no reason to worry, because the Magnusson-Moss Warranty Act has your back. This act ensures that in the instance of a warranty repair, the dealership can’t void your warranty unless they can prove the aftermarket part you installed was the initial cause of the problem
