Dual Quiet Muffler, for Competition Merged Header

EMPI Dual Quiet Muffler for Competition Merged Header

Product Overview and Fitment

The EMPI Dual Quiet Muffler (Part #00-3689-0) is a premium replacement exhaust component designed specifically for competition merged exhaust systems. It features a standard 3-bolt flange and is the correct fitment for EMPI headers 00-3699-0 and 00-7320-0. Built for the air-cooled VW enthusiast who demands performance without the excessive noise of a stinger, this muffler provides a deep, mellow tone while maintaining the flow characteristics required for high-displacement engines.

Pro Tech Tips for Installation

Tip 1: Prep the Raw Steel Finish. This muffler is shipped in raw steel to allow for custom coating. To prevent immediate surface rust, thoroughly clean the muffler with a wax and grease remover, then apply a high-quality, high-temperature header paint or ceramic coating before installation. Do not rely on the shipping oil for corrosion protection.

Tip 2: Ensure a Gas-Tight Seal. When mounting to your 3-bolt flange header, always use a new composite or copper gasket. For an extra layer of protection against leaks, apply a thin bead of high-temperature copper RTV sealant to both sides of the gasket. Tighten the bolts in a circular pattern to ensure even pressure across the flange face.

Tip 3: Verify Body Clearance. Competition merged systems often tuck the muffler closer to the body than standard street exhausts. Before final torqueing, check the clearance between the muffler canisters and your rear apron or bumper. If the fit is too tight, you may need to slightly rotate the header at the head pipes or use exhaust spacers to prevent heat damage to your paint.
