Flexible Exhaust Connector

Design solutions for exhaust vibration and noise control Most front wheel drive(FWD) engines are transversely mounted for compact packaging. This engine orientation results in larger gross engine movements and high levels of vibration being transmitted to the exhaust system because the engine motion is perpendicular to the tailpipe. The best way to provide for motion, thermal compensation, and isolate vibration from the exhaust system is with a flexible exhaust connector.

The application challenge The exhaust system runs very hot and encounters an extremely corrosive and hostile environment. the range of motion between a softly mounted engine and tailpipe can be dramatic. In fact, very rarely is the true operating environment known. Engineering a flexible exhaust connector demands careful attention to engine /chassis dynamics, heat management and corrosion resistance to ensure life-long durability.

Senior Automotive's engineered technology Our thin-wall flexible bellows design solves the motion, noise, vibration and corrosion problems in today's cars. A flexible bellows offers a "leak-free" seal to help meet ever increasing environmental requirements. Our flexible bellows technology absorbs rocking motion, exhaust system motions and isolates vibration from the rest of the exhaust system, so passengers do not experience objectionable noise, vibration or harshness(NVH). As the technology leader, Senior Automotive can design customised exhaust bellows quickly and efficiently.


  • Excellent vibration and durability characterstics.
  • Wide variety of standard mounting flange styles available.
  • Available with or without fittings, for weld-in mounting.
  • Inside diameters from 38mm to 200mm (1.5" to 8.0")
  • Wall thickness from 0.25mm to 0.5mm (.01" to.02") per ply.
  • Multi-ply construction available in all materials; provides longer life and greater durability.
  • Easier installation and parts alignment than with a rigidly mounted exhaust pipe.
  • Flexibility vs. stiffness can be customised as needed
