Exhaust Springs, for Bobcat Style 4 Into 1 Collectors 4 Pack

EMPI Exhaust Springs for Bobcat Style 4-Into-1 Collectors (4-Pack)

Secure Performance for VW Aircooled Exhausts

These EMPI exhaust springs (Part #2555) are designed specifically for the high-vibration environment of aircooled Volkswagen engines. Sold as a 4-pack, these heavy-duty springs provide the necessary tension to securely hold a stinger or collector to the primary pipes on any Bobcat-style 4-into-1 header system. They are a vital component for Dune Buggies, Baja Bugs, and rail jobs that utilize a slip-fit exhaust connection rather than traditional flanges.

Fitment and Application

These springs are compatible with all standard Bobcat-style exhaust systems used on VW Type 1 based engines. If your header features mounting tabs at the collector junction, these springs will provide the reliable retention required for off-road or street use. They are the standard replacement for worn, stretched, or lost springs on EMPI and similar competition-style exhaust systems.

Pro Tech Tips from Appletree Auto

Use a Spring Puller Tool: To avoid barked knuckles and scratched ceramic coating, use a dedicated T-handle spring puller or a loop of heavy-gauge safety wire to stretch the springs into place. Using standard pliers often leads to the tool slipping, which can damage the spring or the exhaust finish.

Vibration Dampening: Apply a small amount of high-temperature RTV silicone or high-temp anti-seize inside the hooks of the springs before installation. This helps dampen harmonic vibrations that can lead to "chatter" wear on the mounting tabs, extending the life of both the springs and your header pipes.

Regular Heat Cycle Inspection: Exhaust springs are subject to extreme heat cycles which can eventually cause the steel to lose its tension. During every oil change, check the tension of your springs. If you can move the stinger or collector easily by hand, the springs have likely stretched and should be replaced with a fresh 4-pack to prevent exhaust leaks or losing your stinger on the trail.
