Flexible and exhaust braid for car without a license: an essential element

The flexible or exhaust a car-free car is a primordial piece to guarantee the good health of your exhaust line and the comfort of driving. Its mission is simple but indispensable: absorb vibrations, compensate for motor movements and preserve the other exhaust components (collector, tubes, silent) against premature wear and cracks.

What is an exhaust hose for?

On a car without a license, the engine is mounted on silent-Blocks and moves slightly during accelerations, braking or load changes. Without flexible, this movement would be directly transmitted to the tubes and the collector, which would cause premature case or leaks.

Vibration absorption

• Reduces the vibrations felt in the chassis.
• Avoids parasitic noises under the floor.
• Protects necklaces, joints and exhaust brackets.
• Improves the longevity of the silencer and the collector.

Compensation of motor movements

The hose acts as a damper. It compensates for motor movements and prevents excessive stresses on the tubes, preserving the tightness of the entire line.

Structure and design of a hose

One exhaust is designed to withstand high temperatures, corrosive gases and repeated vibrations.

Stainless steel braid

The outer part consists of a robust metal braid that protects the inner tube and absorbs mechanical stresses.

Corrugated inner tube

This inner tube is generally made of corrugated steel to allow flexibility and resistance. It ensures the tightness and the correct passage of the gases.

Welding rings and fasteners

The ends of the hose comprise welded rings or sleeves that facilitate assembly with exhaust tubes and ensure a durable connection.

Signs of wear of a hose or a braid

An end-of-life flexible causes various symptoms easily identifiable.

Sound indicators

• Breathing noise under the car.
• Sound level higher at acceleration.
• Slapping metal when the braid disintegrates.

Visual signs

• Braided part frayed or broken.
• Traces of soot around the hose.
• Visible leaks of slow motion gas.
• Abnormal displacement of the exhaust line.

Consequences of a defective flexible

Ignore a damaged hose can lead to expensive repairs.

Mechanical consequences

• Crack of the collector or tubes.
• Breakage of the exhaust line brackets.
• misalignment of the line and risk of silent breakage.
• Loss of counter-Engine pressure and torque drop.

Consequences on comfort and security

• significant increase in noise in the passenger compartment.
• Odor of gases that can rise in the vehicle.
• Risk of cons-Visit during technical control.

Maintenance and prevention

Regularly check the condition of the braid and fasteners avoids more severe failures.

Recommended controls

• Visual inspection every 10,000 km.
• Check the absence of soot or leak around the hose.
• Make sure that necklaces and supports are tight.
• Check the condition of the exhaust manifold which can also be weakened.

Good practice

• Replace the hose from the first signs of leakage.
• Always change the seals and necklaces when mounting a new hose.
• Check the silent-blocks and line supports at the same time.
• Use a quality hose to avoid too frequent replacements.

Replacing a hose or a braid

The mounting of a hose must be carefully made to guarantee sealing and durability.

Main steps

• Allow the exhaust line completely.
• Disassemble the fixing clamps and remove the worn part.
• Position the new flexible without constraint or twisting.
• Tighten the necklaces gradually for optimum sealing.
• Check that the line does not touch the chassis or other elements.

Check after assembly

• Start the engine and listen to the noise: no leak should be perceived.
• Make a road test to confirm the removal of vibrations.
• Reconstrox tightenings after a few kilometers.
