5 Inch Diesel Exhaust Tip With 135° Turn-Down
This 5 inch side-exit exhaust tip is designed for boats with a 5” outer diameter exhaust pipe. The 135° turn-down directs exhaust away from the hull, helping reduce water spray and exhaust residue. Best for vessels needing a bolt-on, no-weld solution and simple retrofit. The kit is suited for owners who want straightforward installation and a durable stainless steel build.
Who it’s best for: Boat owners with a 5” OD tailpipe seeking an easy, bolt-on upgrade that minimizes rust risk. Why selected: It combines a precise fit with a turn-down design to improve flow and reduce hull exposure to exhaust residue.
Limitations: Verify 5” OD tailpipe compatibility (not ID) before purchase; incorrect diameter can require alternative fittings or adapters. For best results, professional installation is recommended.
316L Stainless Marine Through Hull 4″ Tip
This 316L stainless steel exhaust tip offers mirror-polished durability ideal for through-hull installations. Its corrosion resistance makes it a strong choice for saltwater environments. It’s best for builders prioritizing long life and a clean, high-gloss finish on through-hull systems.
Who it’s best for: Mariners needing a through-hull solution with premium corrosion resistance. Why selected: 316L stainless steel provides exceptional durability in harsh marine conditions.
Limitations: Through-hull configurations require precise cutting and sealing; ensure fitment in your hull design and follow proper marine installation methods.
Exhaust Tip 3″ Inlet / 4″ Outlet, Dual Slant
This dual-slant exhaust tip features a 3” inlet and 4” outlet with a 16” length, offering a flexible left or right-side weld-on option. The dual-slant design helps channel exhaust gas efficiently while enabling installation on multiple sides of the vessel.
Who it’s best for: Boat builders or DIY installers needing a versatile, left-right compatible weld-on tip. Why selected: The dual-slant arrangement increases alignment options on various hull layouts.
Limitations: Requires welding; not a bolt-on retrofit. Confirm your pipe diameter and required inlet/outlet compatibility before ordering.
4 Inch Chrome Plated Diesel Elbow Tip
This chrome-plated diesel exhaust elbow tip has a 4” inlet and 5” outlet with a 23” overall length. The polished chrome finish provides a striking look while the 45-degree elbow directs exhaust away from the hull surface, reducing exposure to the deck and side rails.
Who it’s best for: Owners seeking a chrome finish with a longer reach for better exhaust routing. Why selected: The length and angle help manage exhaust trajectory away from sensitive surfaces.
Limitations: Chrome plating adds aesthetic appeal but can require careful maintenance to prevent surface wear. Ensure compatibility with your exhaust diameter and mounting options.
Diesel Exhaust Elbow Tip, Side Exit Chromed
This chromed side-exit exhaust tip offers a 4” inlet and 6” outlet configuration for side routing and a broader exhaust footprint. The chrome finish provides corrosion resistance and a polished appearance. Suitable for universal diesel exhaust setups in boats and larger vehicles.
Who it’s best for: Vessel owners needing a chromed, durable side-exit tip with a longer outlet. Why selected: The 6” outlet expands exhaust dispersion and helps reduce back-pressure concerns on certain layouts.
Limitations: Universal fit means verifying pipe diameter and mounting compatibility. Chromed surfaces may require care to maintain shine in harsh marine environments.
Buying Guide: Marine Side Exhaust Tips
What matters most when selecting
- Fitment: Confirm tailpipe diameter (OD vs ID) and inlet/outlet sizes match your boat’s exhaust system.
- Material and finish: Stainless steel (316L) resists corrosion; chrome plating offers a polished look but may require maintenance in saltwater environments.
- Configuration: Side exit, through-hull, and weld-on options suit different hulls and mounting approaches. Choose bolt-on when you want a simple retrofit; weld-on for a permanent install.
- Length and angle: Longer tips and specific angles direct exhaust away from surfaces, reducing residue and heat impact on the hull.
- Installation method: Bolt-on tips require no welding; weld-on tips demand accurate alignment and sealing. Consider professional installation for best results.
- Durability: Look for forged or mandrel-bent tubing and high-quality finishes that withstand vibration and marine exposure.
Better for and choose this if
- Better for easy retrofits: Bolt-on tips with standard 5” or 4” OD tails.
- Better for saltwater boats: 316L stainless or high-grade chrome finishes.
- Choose this if you need a through-hull installation: Ensure hull design supports a through-hull configuration.
Quick compatibility checklist
- Exhaust pipe diameter must match the tip inlet/outlet sizes.
- Check hull clearance behind the exhaust outlet to avoid overheating neighboring components.
- Inspect for water intrusion risk, especially with turn-down and elbow designs.
- Confirm the installation method (bolt-on vs weld-on) aligns with your capabilities or professional help.
FAQ
- Q: Do these tips reduce exhaust noise? A: They can influence sound by directing flow, but primary purpose is routing and protection from residue.
- Q: Can I install these myself? A: Bolt-on tips are DIY-friendly; weld-on tips require welding tools and care.
- Q: Will chrome tips rust in saltwater? A: Chrome-plated finishes resist corrosion, but regular maintenance helps maintain appearance.
- Q: Can I mix tips on opposite sides of the boat? A: Yes, but ensure uniform performance and mounting specifications for balance and exhaust flow.
- Q: How do I verify the correct fitment? A: Compare your exhaust pipe outer diameter to the tip inlet size and confirm the length and outlet size match your routing needs.
- Q: Are these tips designed for diesel exhausts only? A: They are marketed for diesel and general exhaust systems; verify compatibility with your engine type and exhaust configuration.
