Quiet the drone and restore a factory-tuned exhaust note with the AP Exhaust Muffler 2589. This baffled, direct-fit OE-replacement muffler drops into the listed applications, including the 2007-2010 Chevrolet Silverado 2500 HD and 3500 HD [V8-6.0L], the 2007 Silverado 2500 HD Classic and 3500 Classic [V8-6.0L, V8-8.1L], the 2007-2010 GMC Sierra 2500 HD and 3500 HD [V8-6.0L], and the 2007 Sierra 2500 HD Classic and 3500 Classic [V8-6.0L, V8-8.1L] — see the Buyer's Guide tab for the full list.

  • Aluminized steel body: constructed from 100% aluminized steel for corrosion resistance.
  • OE tuning: Original Equipment tuning is engineered to match OE tone, with an OE-comparable sound level.
  • Direct-fit design: a baffled muffler with a 3.5 in right-center inlet and a 3.5 in left-center pipe outlet, measuring 20 in body length and 26 in overall.
  • Backed by a Limited Lifetime Warranty.

The muffler dampens exhaust pulses as gases pass through its internal baffling to reduce noise. Signs the original may need replacing include a loud or droning exhaust, rattling from broken internal baffles, or rust-through and leaks. No heat shield is attached, and this unit is not tunable. Made in the United States.

Manufacturer's Warranty: Limited Lifetime Warranty.
