Product Overview

Upgrade your aircooled VW with the premium EMPI Stainless Phat Boy Muffler. Engineered for performance and longevity, this muffler is constructed from high-quality stainless steel to resist corrosion and maintain a professional finish.

Vehicle Fitment & Compatibility

This muffler is designed for use with all Type 1 Volkswagen engines. It is an ideal performance upgrade for VW Beetles, Karmann Ghias, and Dune Buggies. To ensure a proper fit, verify that your header or extractor uses the standard 1:00 flange clocking. This unit is the perfect match for the EMPI 00-3767-0 extractor, providing a deep, throaty exhaust note without sacrificing ground clearance.

Pro Tech Tips for Installation

Use High-Temp Anti-Seize: Always apply a small amount of high-temperature anti-seize lubricant to the threads of the mounting hardware. Stainless steel fasteners are prone to "galling" or seizing; this simple step ensures you can easily remove or adjust the muffler in the future.

Clean Before Starting: Before you fire up the engine for the first time, wipe down the entire stainless muffler with a clean rag and rubbing alcohol or a specialized stainless cleaner. Fingerprints and oils left on the metal can "bake" into the surface during the first heat cycle, causing permanent stains or discoloration.

Perform a Heat-Cycle Torque: After your first 50 to 100 miles of driving, re-check the tightness of the flange bolts. The thermal expansion of the stainless steel and the compression of the new gasket can cause hardware to loosen slightly. A quick re-torque prevents exhaust leaks and protects the gasket from blowing out.
