Quiet your exhaust and route spent gases cleanly with the AP EXHAUST muffler (MPN 700394), a direct-fit replacement for the 1996-2002 Toyota 4Runner with the V6-3.4L engine. This baffled muffler drops into the factory location and uses internal baffling to dampen combustion noise as exhaust flows through.
