3" Catalytic Converters

3″ Universal Catalytic Converters

Our 3″ universal catalytic converters are the ultimate choice for performance vehicles, turbo builds, V8s, and high-output diesel setups. Designed for maximum flow without compromising emissions, these high-flow metallic cats are perfect for custom exhaust systems where compliance and performance go hand in hand.

These converters feature a durable stainless or mild steel body with a 100-cell or 200-cell metallic substrate—delivering excellent heat tolerance and flow characteristics even under extreme conditions.

For a complete custom fit, pair your 3″ cat with:

• 3″ mandrel bends for seamless routing
• Steam pipe sections for heavy-duty manifold fabrication
• 3-bolt flange plates and gaskets for tight sealing
• V-band clamps or butt clamps for fast install and removal
• Bolts & nuts to secure everything in place
