| 1 | Symmetrical Twin Round Tips Balanced appearance | Inlet: 50–76 mm Outlet: 2 × 76–101 mm | 304 stainless steel; polished or brushed finish | Clamp-on or welded to a dual-outlet rear section | Passenger cars and light commercial vehicles requiring a conventional dual-exit layout | Usually a cosmetic component when it does not alter the exhaust path, silencer, catalyst, particulate filter, or noise-control system. Vehicle-level sound approval under UNECE R51.03 remains applicable where required. |
| 2 | Black Coated Twin Round Tips Low-reflection finish | Inlet: 50–76 mm Outlet: 2 × 76–101 mm | Stainless steel with high-temperature ceramic or thermal coating | Clamp-on, sleeve fit, or welded installation | Modern exterior styling and vehicles with dark trim packages | Verify coating temperature resistance and clearance from bumpers. The finish itself does not establish ECE, EPA, or CARB approval; any change to emissions or acoustic performance must be assessed separately. |
| 3 | Angled-Cut Twin Tips Sport-oriented style | Inlet: 57–76 mm Outlet: 2 × 76–102 mm | 304 stainless steel or aluminized steel | Weld-on or adjustable clamp-on installation | Vehicles with a sloped rear bumper or a performance-style appearance | Cut angle and projection should remain within local bodywork and road-safety requirements. Do not assume that a visual tip carries an “ECE” approval unless a valid approval marking and supporting documentation apply to the complete system. |
| 4 | Rolled-Edge Twin Tips Reduced sharp-edge risk | Inlet: 50–70 mm Outlet: 2 × 70–95 mm | 304 stainless steel with rolled lip | Clamp-on or welded installation | OEM-style replacement and comfort-focused exterior upgrades | Rounded edges may support safer body integration, but they do not replace vehicle-level safety or noise testing. Check that the tip does not redirect exhaust toward the passenger compartment or heat-sensitive components. |
| 5 | Slash-Cut Twin Tips Aggressive styling | Inlet: 57–76 mm Outlet: 2 × 76–102 mm | 304 stainless steel or titanium alloy | Weld-on installation recommended for high-temperature applications | Performance vehicles and motorsport-inspired road styling | Confirm that the design does not increase noise, bypass a silencer, or interfere with an approved emissions-control layout. In the United States, emissions-related modifications may trigger EPA anti-tampering concerns and CARB requirements. |
| 6 | Double-Wall Insulated Twin Tips Heat management | Inlet: 50–76 mm Outlet: 2 × 76–101 mm | Double-wall stainless steel with an air gap | Clamp-on or welded installation with heat-clearance inspection | Vehicles with close bumper cut-outs or heat-sensitive exterior materials | Double-wall construction can reduce outer-surface temperature, but it is not an emissions or noise certification. Maintain the manufacturer’s clearances and ensure that drainage and exhaust flow are not restricted. |
| 7 | Inlet-Reducer Twin Tips Mixed pipe sizes | Inlet: 45–63 mm Outlet: 2 × 70–89 mm | Aluminized steel or 409 stainless steel | Clamp-on with adapter sleeve; welding may be required | Older vehicles or replacement systems with smaller tailpipes | Measure the actual pipe outside diameter before ordering. A reducer should not create a significant obstruction or leakage. Exhaust back-pressure, sound level, and emissions performance must be verified at vehicle level when the flow path is changed. |
| 8 | High-Clearance Twin Tips Off-road and utility fit | Inlet: 50–76 mm Outlet: 2 × 63–89 mm | 409 stainless steel or aluminized steel | Weld-on or heavy-duty clamp-on mounting | Light commercial vehicles, utility vehicles, and vehicles exposed to rough roads | Check ground clearance, suspension movement, tow-bar clearance, and heat shielding. Off-road use does not automatically exempt a vehicle from public-road noise or emissions requirements. |
| 9 | Oval Twin Tips Wide bumper opening | Inlet: 50–76 mm Outlet: 2 × 90–130 mm wide | 304 stainless steel or coated steel | Clamp-on, welded, or fabricated rear-section installation | Wide diffuser openings and vehicles requiring greater visual coverage | Confirm bumper opening dimensions and avoid excessive outlet area that may affect appearance, heat distribution, or acoustic behavior. Approval status belongs to the complete exhaust configuration, not merely the oval tip shape. |
| 10 | Universal Adjustable Twin Tips Flexible fitment | Inlet: 45–76 mm adjustable Outlet: 2 × 63–101 mm | 304 stainless steel with adjustable sleeves | Clamp-on installation; periodic fastener inspection required | Multi-market inventory and vehicles with uncertain tailpipe dimensions | Suitable only when securely mounted and correctly aligned. Universal fit does not mean universal legal compliance. Confirm local type-approval, noise, emissions, marking, and installation rules before import or road use. |
