Exhaust tailpipe adapters

Start 9 Exhaust technology 9 Exhaust tailpipe adapters

Exhaust tailpipe adapters

For direct and nearly gas tight evacuation of exhaust gas at the tailpipe of the cars on the dynamometer.

Depending on the requirements of the tests and the adaptation possibilities on the car, there are different types and designs.

Please contact us directly so we could discuss your requirements for the fitting adapter.

or

Therefore we need the following information:

  • Vehicle series, engine data, performance data

  • year of manufacture
  • requirements of tests – this primarily relates to temperature and tightness requirements. And also possibilities/requirements of temporary or fix installations at the vehicle.
  • favored flange form

Overview about the adapters and different types

 

We have developed a wide range of adapters for various car manufactures.

We would be happy to develop any kind of adapter that hasen´t been developed yet.

The necessary information and data for the development process is described below.

    Development process

    For developing an adapter we use modern technology like 3D CAD und 3D printing for testing and rapid prototyping.

     

    For the needed vehicle normally we will get provided the CAD data.

    If this is not possible we also can take measurements on the vehicle or we need provided a muffler complete with end pipes.

    We will design and customize  the adapter in 3D CAD.

    For testing the prototype we are able to print the end pipe data with a 3D printer.
    So we can easy check and adjust the fitting and clamping.

    The finished adapter is ready to use and reproducible.

    Construction types

     For the right decide of the needed type of adapter there are following the most important properties:

     

    Adaptertype
    ShortCodes
    Tightness
    Usability
    thermal stability
    Vehicle interference
    Adapter with mechanics and seal in outer clamping
    KAA
    tight
    no tool necessary
    limited, circa 220°C long-term loading
    mostly no change is necessary. Sometimes the removal of the molding or rear valance is necessary.
    Adapter with mechanics and seal in inner clamping
    KAI
    tight
    no tool necessary
    limited, circa 220°C long-term loading
    mostly no change is necessary. Sometimes the removal of the molding or rear valance is necessary.
    Adapter in design of glasses, mount at end of pipe profile
    BR
    tight
    tool is necessary
    with graphit seal up to 600°C
    mostly no change is necessary. Sometimes the removal of the molding or rear valance is necessary.
    Adapter with clamp (absolute metallic)
    KAM
    limited tightness
    tool is necessary
    hight long-term loading possible
    mostly no change is necessary. Sometimes the removal of the molding or rear valance is necessary.
    Welding adpater
    AA
    tight
    pre-assembled
    hight long-term loading possible
    silencer will be changed and adapter is welded.

    An overview of different adapter types are shown in the gallery top right.

    The costs depends on the types of construction and effort. Above you will find some examples:

    Excaust tailepipe adapter with mechanics and silicon seal

    The ring of silicon as seal is clamped in longitudinal direction. So it can seal up to the end pipe.

    There are two ways to clamp. The apdater is on the outside and seals up to the outer shape of the tailpipe or it is inside and clamps to the inner shape.

    Weldingadapter

    The adapter is welded to the tailpipe.
    Thus, it is absolutely tight to the environment and insensitive to high temperatures.

    Exhaust Adapter with gripper clamp (absolute metallic)

    The adapter is clamped to the end pipe with hose clamps.

    There are no temperature sesitive seals. So this adapter can stand high temperature but is restricted in thightness.

    Other Adapter

    Simple adapters for round and oval profiles.
    The connection is made with silicon hoses and hose clamps.

    In order of the connection there is a great surface of the silicon hose in contact with the exhaust. 
    That can be have a negativ effect to the results from exhaust measurements.
