Muffler, Exhaust & Emissions System

Modification & Repair Services

Your car not only has to help keep your family safe, it has to do its part to keep the planet safe. Your vehicles exhaust system is crucial to your engine performance. Modern exhaust systems do a lot more than reduce noise condition or remove exhaust gases from the vehicle. They are built to meet the exact specifications of your engine.

That’s why you need a Certified Technician to inspect and diagnose your system. Your system may need to be tested for back pressure, which can make your engine lose power, stall or even stop running if it is too high. The amount of oxygen as a percent of exhaust gases may need to be measured.

Your exhaust system needs to be check regularly. It is indeed subjected to hard test: high-temperature changes frequently, internal corrosion by acidity and gas residues, external corrosion by water and salt. Rubbers, clamps or springs which maintain the muffler must be controlled frequently.

- Rattling noise.
- Loud noise while driving.
- Unpleasant gasoline burnt smell.

Anti-Pollution System

We tend not to think about it, but your car's emissions system plays a very important role. In addition to reducing the noise emitted by your car and harmful emissions for the environment, it prevents your vehicle from filling up with dangerous gases.

If your Check Engine Light refuses to turn off, it is important not to ignore it. This could indicate a problem with your emissions system or oxygen sensor.

Inspection the condition of the exhaust manifold, the condition of the catalytic converter, the oxygen sensors, the intermediate resonator, the rear silencer, the wear of the fixing parts, the exhaust pipes, protectors (heat shields) and checking the DEF diesel exhaust fluid level (topping up if necessary).

Inspection of the air intake system air filter, intake manifold, intake valves, idle air control (IAC) valve, mass air flow meter ( MAF) and intake tubes.



Air intake system maintenance replacing air filter, intake valves and cleaning air intake system.

Fuel system maintenance fuel filter replacement, injector cleaning and throttle valve.

Internal Engine Maintenance is the perfect solution for such cleaning. Highly effective cleaning additives dissolve deposits and dirt. They are then evacuated with the used oil during draining. The engine is less subject to wear. The evacuation of exhaust gases is optimized and a lack of lubrication is avoided.



Warning light (Check Engine), if the engine light comes on, a Scanner analysis to read the error codes. Exhaust and emissions system codes can help you identify specific problems.

Oxygen sensors (or lambda sensors), monitor the air-fuel mixture and contribute to the proper functioning of the antipollution system. Tests the condition and operation of oxygen sensors, and replaces if necessary according to the manufacturer's recommendations.

Road Test

A road test of the vehicle before delivery, using several simulations and driving maneuvers to test the performance of the engine and transmission at acceleration and at idle to ensure the proper functioning of the systems and that no fault lights come ON.

Expert Advice

  • Off-Road Driving

    When driving Off-Road your vehicle's exhaust and emissions systems may be subjected to more extreme conditions than during normal on-road driving. Here are some tips for caring for these systems when driving Off-Road:

    Exhaust System:

    - Before going on an off-road excursion, visually inspect the exhaust system for damage, such as leaks, cracked welds, or loose components.

    Damage Protection:
    - Install exhaust system guards, such as skid plates, to protect the pipes and mufflers from rocks, branches, and other obstacles encountered while driving Off-Road.

    Avoid Obstacles:
    - Try to avoid driving over obstacles that could damage the exhaust system, such as sharp rocks or tree trunks.

    Cleaning After Use:
    - After each Off-Road trip, inspect the exhaust system for potential damage and clean it to remove mud, dirt and debris that may have accumulated.

    Checking Fasteners:
    - Make sure all exhaust system fasteners are tight to avoid excessive vibration which could damage components or cause leaks.

    Anti-Pollution System:

    Regular Maintenance:
    - Follow the manufacturer's recommendations for maintaining the emissions system, such as replacing air filters and oxygen sensors at regular intervals.

    Using Clean Fuel:
    - Use quality fuel and avoid poor quality fuel, which can clog fuel injectors and exhaust treatment systems.

    Monitoring Fault Codes:
    - Monitor engine fault codes and have any emissions-related problems diagnosed as soon as they are detected.

    Avoid Overheating:
    - Avoid running the engine at excessive temperatures, as this can damage emissions system components such as the catalyst.

    Timely Repairs:
    - If problems are detected with the emissions system, have the necessary repairs made as soon as possible to avoid damage to other engine or exhaust system components.

  • Service Tips

    When looking for tips on maintaining your vehicle's exhaust and emissions system, here are some service recommendations:

    Regular Maintenance:
    - Schedule regular exhaust and emissions system checks during your regular maintenance appointments. This will help detect potential problems before they become more serious.

    Visual Inspection:
    - Have the exhaust system visually inspected for signs of corrosion, leaks or damage. Make sure all fasteners are tight.

    Emissions Test:
    - If your vehicle is subject to periodic emissions testing, make sure it passes these tests. If you notice increased emissions or pollution-related error codes, have the problem diagnosed promptly.

    Use A Quality Fuel:
    - Use quality fuel and avoid cheap, inferior fuels. Poor quality fuel can clog fuel injectors and damage emissions system components.

    Replacing air filter:
    - Replace engine air filters regularly to maintain good air flow and reduce polluting emissions.

    Avoid Overheating:
    - Avoid running the engine at excessive temperatures, as this can damage emissions system components, including the catalyst.

    Timely Repairs:
    - If you notice symptoms of problems with the exhaust or emissions system, such as abnormal noises or unusual emissions, have the problem diagnosed and repaired as soon as possible to avoid damage to other vehicle components.

    Consultation A Professional:
    - If you are unsure about the condition of your exhaust or emissions system, consult a qualified automotive service professional. They can perform thorough inspections and recommend necessary repairs.
