Sideflow Exhaust System, for Beetle, Type 1 Engines

EMPI Sideflow Exhaust System for VW Beetle Type 1 Engines

Vehicle Fitment and Compatibility

The EMPI Sideflow Exhaust System (Part # 00-3485-0) is engineered specifically for Volkswagen Type 1 and Type 2 engines ranging from 1300cc to 1600cc, provided they utilize an upright cooling configuration. This system is a popular performance upgrade for the VW Beetle, offering a significant improvement over stock restrictive exhausts. It features 1-1/2 inch mandrel-bent tubing and a true 4-into-1 merged collector, which is TIG welded for maximum structural integrity and a clean, professional appearance.

Performance Design and Features

This exhaust kit is designed to balance backpressure and improve exhaust scavenging, resulting in better throttle response and a deeper engine note. The system includes a black quiet muffler to keep decibel levels manageable while maintaining a performance edge, accented by a polished chrome tip for a classic look. Appletree Auto provides this kit complete with all necessary gaskets and hardware required for a straightforward installation on your aircooled power plant.

Pro Tech Tips from Appletree Auto

Tip 1: Heat Cycle Re-Torquing. Exhaust gaskets on aircooled VW engines often compress after the first few miles of driving. To prevent leaks at the cylinder head, we recommend running the engine to operating temperature, letting it cool completely, and then re-torquing the header nuts to ensure a permanent, airtight seal.

Tip 2: Surface Preparation and Protection. While the muffler comes with a black finish, the high operating temperatures of a Type 1 engine can be harsh on standard coatings. For maximum longevity, wipe down the header pipes with denatured alcohol before the first start to remove oils from your hands, and consider applying a high-temp ceramic coating to prevent surface oxidation over time.

Tip 3: Verify Apron Clearance. The Sideflow design alters the exit point of the exhaust compared to a stock "pea-shooter" setup. Before finalizing the installation, mock up the muffler to ensure there is adequate clearance between the chrome tip and your Beetle's rear apron or fender. Proper spacing prevents heat-related paint bubbling and vibration noise against the bodywork.
