Product Details

The AP Exhaust 3599 is a Challenge Series OE replacement muffler built from aluminized steel for long-lasting corrosion resistance. Engineered as a direct-fit replacement, it installs without modifications, restoring exhaust performance to factory specifications.

AP Exhaust's Challenge Series mufflers are designed to deliver a subtle but noticeable improvement in exhaust tone while remaining refined and daily-driver friendly — more sound presence than stock without harshness or drone.

Key Features:

  • Direct-fit OE replacement — no cutting or modifications required for installation
  • Patented Single Cartridge Muffler Design for improved performance and extended service life
  • Aluminized steel construction — heads, shell, and wrapper for durability and corrosion resistance
  • Fully welded necks for enhanced durability and a leak-free seal
  • All required support brackets welded to the muffler body for long-lasting strength
  • Minimum back-pressure and maximum sound control to perform at OE levels
  • Limited Lifetime Warranty backed by AP Exhaust

The AP Exhaust Challenge Series represents the brand's best OE replacement muffler line, designed using 3-D modeling programs to ensure a precise fit. Each unit is individually boxed for added shipping protection.
