Flexible Pipes for Exhaust Systems: Technical Specifications and Quality Features
Flexible pipes (flexible sections) perform a critical mechanical compensation function in modern automotive exhaust systems. As flexible intermediate sections, they minimize the transmission of engine-induced vibrations, torsional forces, and cyclic loading to the rest of the exhaust system. Without this decoupling, the continuous vibration load inevitably leads to stress cracks in rigid components such as the exhaust manifold, the catalytic converter, or the muffler housings. Turbo-parts supplies technically advanced flexible pipes that can withstand the highest thermomechanical demands over the long term.
Design Features: Stainless steel mesh with Interlock technology
The Stag Flex hoses available at Turbo-parts.de feature a three-layer or reinforced construction. The outer braid consists of high-alloy stainless steel mesh, which offers high tensile strength and protects the component against external mechanical influences and corrosion. Inside is a highly stable interlock system (corrugated metal hose profile). This design optimizes exhaust flow, prevents flow turbulence, and provides additional protection for the flexible pipe against the thermal stress of hot exhaust gases, which significantly increases its service life compared to simple liner systems.
Dimensions and Size Availability
For proper repair or modification of the exhaust system, the dimensional accuracy of the replacement part is crucial. The product range covers all standard pipe diameters to adequately serve both production vehicles and performance-enhancing custom exhaust systems (motorsports / tuning):
| Standard Diameter | Intermediate Sizes | Applications (Examples) |
|---|---|---|
| 38 mm | – | Small cars, older vehicle models, bypass lines |
| 60 mm | 65 mm | Standard Series Systems (Mid-Range, Diesel Generators) |
| 63.5 mm (2.5 inches) | 70 mm | Sport exhaust systems, optimized downpipes |
| 76 mm (3 inches) | – | High-performance turbocharged vehicles, aftermarket exhaust systems |
| 89 mm (3.5 in) | – | High-performance applications, large-volume downpipes |

Selection and Installation Instructions
To determine the correct flexible pipe, both the outer diameter of the pipe and the total length of the section to be replaced must be precisely measured. Since flexible hoses are typically welded in place, care must be taken during installation to ensure stress-free tack welding and a properly executed weld (preferably TIG/MIG with a suitable stainless steel filler metal) to avoid adversely affecting the material properties of the stainless steel mesh.
