Catback

A catback exhaust system replaces the factory exhaust components from the catalytic converter back to the tailpipe. This collection includes complete kits that bolt to the stock catalytic converter location, offering an upgrade in flow, sound, and often appearance.

Typical catback designs feature larger-diameter mandrel-bent tubing to reduce restriction, paired with straight-through or chambered mufflers that deliver a more aggressive exhaust note. Materials range from aluminized steel for budget longevity to stainless steel for maximum corrosion resistance.

When choosing a catback, consider:

  • Pipe diameter: Affects flow and sound; too large can sacrifice low-end torque.
  • Material: Stainless steel resists rust best, especially in wet or salted areas.
  • Muffler design: Chambered for a deep tone, straight-through for maximum flow and volume.
  • Tip style: Single, dual, or quad tips in various finishes to match your aesthetic.
  • Vehicle fitment: Ensure proper hanger locations and routing for your make and model.

Whether you're chasing performance gains or a more thrilling exhaust note, our catback collection has options for a wide range of applications.
