Designed for high efficiency, it provides a cleaner look and better flow than stock configurations. This system is a popular choice for owners looking to unlock the potential of the Type 4 engine platform.

This exhaust system is designed to fit the 1975 through 1978 VW Type 2 Bus as well as 411 and 412 models equipped with Type 4 engines. Please note that this system eliminates the catalytic converter. It is not legal for street use in California and is intended for off-road or competition use in restricted regions.

Pro Tech Tips from Appletree Auto

Replace Every Gasket: Do not reuse old exhaust gaskets. Installing fresh gaskets ensures a perfect seal and prevents exhaust leaks that can cause backfiring or poor engine performance. A small leak at the head can lead to burnt valves over time.

Examine Mounting Studs: Before installation, inspect the studs on your heat exchangers. If they show signs of heavy rust or fatigue, replace them now to avoid broken hardware during the tightening process. Using a high-quality anti-seize lubricant on the threads will make future maintenance much easier.

Verify Air Fuel Mixture: Because this performance system improves exhaust flow, it can sometimes cause a lean running condition. Check your spark plug color after the first few miles of driving to determine if your carburetor or fuel injection system requires a slight adjustment to compensate for the increased flow.
