Bevinsee 3″ Escape Pipe Fender Exit Bezel

The Bevinsee bezel uses 6061-T6 aluminum for a light yet sturdy fit. Its anodized surface provides rust and corrosion resistance for longer life in harsh marine environments. The flange inside diameter is 3.1″, with an outside diameter of 4.875″. This makes it best for vessels that require a precise 3.1″ ID bezel and don’t need extra heavy-duty stainless construction. Best for: light to mid-weight craft where corrosion resistance and weight saving matter. Caution: Ensure compatibility with your exhaust pipe diameter and mounting pattern, as the 3.1″ ID is a fixed spec.
Why chosen: It balances durability and weight while delivering a clean finish to the side exit, suitable for smaller powerboats or dinghies that need a sleek upgrade without bulk.
Aluminum Exhaust Bezels Black Chrome Side Exit

This bezel is finished in black chrome and focuses on a quick cosmetic upgrade for side exit exhausts. It is a simple, affordable solution for vessels that want a low-profile, uniform look without the need for heavy-duty fabrication. Best for: boats needing a sleek, non-reflective finish and an easy install. Caution: The listing emphasizes color and finish; verify fit with your specific pipe size and mounting footprint to avoid mismatches.
Dirt King Fabrication Side Exit Bezels

The Dirt King option is built from stainless steel with an inner diameter of 3.5″ and a 0.05″ thick cut. It features eight mounting holes at 1/4″ diameter for robust attachment. Best for: boats requiring a durable, corrosion-resistant bezel with a larger ID for higher exhaust flow. Caution: Heavier construction means more weight; ensure mounting space and bolt pattern compatibility with your transom assembly.
MBRP S5236AL 3″ Aluminized Steel Single Side Exit

The MBRP system combines a polished look with performance benefits. While it highlights mirror-polished T304 exhaust tips and claims to boost torque and horsepower, the key takeaway is a balanced upgrade for those seeking a complete side exit system rather than a simple bezel. Best for: buyers prioritizing performance-oriented exhaust routing with a refined appearance. Caution: System-level improvements depend on vehicle and engine configuration; confirm compatibility with emissions and overall exhaust design.
Diesel Exhaust Elbow Tip, Side Exit

The Diesel Exhaust Elbow Tip from Floshine features a chromed finish and a high-strength alloy steel construction designed to resist rust at high temperatures. It is a universal fit for diesel exhaust systems, accommodating a wide range of vehicles including cars, pickups, and trucks. Best for: diesel-powered applications requiring a durable, reflective tip with a smooth look. Caution: Universal fit can require additional adapters or trim to ensure a clean installation on non-standard pipes.
Buying Guide
Key purchase considerations help identify the right side exit option for your boat and engine setup.
- Materials and corrosion resistance: Aluminum is lightweight and resistant to corrosion; stainless steel offers maximum durability in saltwater, while chromed finishes adjust aesthetics.
- Diameter and fit: Confirm the inner diameter (ID) and outer dimensions to match your exhaust pipe and mounting holes.
- Finish and appearance: Choose between matte, black chrome, or polished finishes based on preference for visibility and maintenance.
- Mounting requirements: Consider eight-hole patterns, bolt size, and whether a bezel is decorative or structural.
- Performance implications: Some options claim torque or horsepower benefits; verify whether the product supports your engine’s exhaust routing and backpressure goals.
- Application scope: Universal tips fit multiple vehicles; dedicated side exit bezels fit specific pipe sizes and mounting footprints.
- Maintenance needs: Anodized or coated surfaces reduce corrosion but may require periodic cleaning to maintain appearance.
