As Seen on Car SOS: A Testament to Expertise
One of the most compelling endorsements of Mij Exhausts' capabilities comes directly from their involvement with the hugely popular television series, Car SOS. Since its inception in 2013, Car SOS has captivated audiences by restoring cherished classic cars across the UK and Europe, often under challenging circumstances, to surprise their deserving owners.
Mij Exhausts had the distinct pleasure of collaborating with the show's charismatic hosts, Tim Shaw and Fuzz Townshend, right from their very first season. Their expertise was crucial in supporting the restoration of a Fiat 850 Spider belonging to an injured individual, a project that required meticulous attention to detail and a sympathetic approach to bring the vehicle back to its former glory. This memorable collaboration can be seen in Season 1, Episode 4, aptly titled 'Fiat Fiasco', where Mij Exhausts' contribution played a vital role in the successful completion of the restoration. This early involvement with such a high-profile show immediately established their credibility and showcased their ability to tackle complex exhaust challenges with precision and skill, reinforcing their standing as true experts in their field.
Beyond the Brands: Mij Exhausts' Unrivalled Expertise
While the quality of the exhaust system itself is paramount, the expertise of the installers is equally crucial for optimal performance and longevity. Mij Exhausts prides itself on its 'old school mechanics' approach, combining years of hands-on experience with a keen diagnostic eye. This commitment to thorough, knowledgeable service is perhaps best illustrated by the experience shared by a satisfied customer, Jahmaine Merchant, who brought his Jaguar in with a restricted performance problem.
Jahmaine's account highlights the diagnostic prowess of the Mij Exhausts team, particularly Alex. Despite their busy schedule, Alex quickly identified the issue, which turned out to be a manifold leak. What truly set Mij Exhausts apart was Alex's dedication to saving the customer money, even going out of his way to source a sensor from another garage to avoid an unnecessary £140 expense. This level of customer care, combined with their recommendation for a smoke test to definitively confirm the leak, demonstrates a transparent and highly professional service. It's this blend of technical acumen and genuine concern for the client that makes Mij Exhausts a highly recommended establishment, earning them an impressive 11/10 for service from Jahmaine. Their French mechanic also receives high praise, underscoring the depth of knowledge within the team.
How a Customised Exhaust System Improves Your Performance
A vehicle's exhaust system is far more than just a pipe that expels gases; it's a finely tuned component that significantly influences engine efficiency, sound, and overall vehicle performance. A customised or upgraded exhaust system can unlock several key benefits:
- Increased Horsepower and Torque: Factory exhaust systems are often designed with noise reduction and cost-effectiveness as primary concerns, leading to restrictive bends and smaller piping. A performance exhaust system, with its larger diameter, smoother bends, and less restrictive mufflers, allows exhaust gases to exit more quickly and efficiently. This reduces backpressure on the engine, enabling it to 'breathe' better and produce more power.
- Improved Fuel Efficiency: While often associated with power gains, a more efficient exhaust system can also contribute to better fuel economy. By reducing the workload on the engine to expel gases, it can operate more efficiently, potentially leading to slight improvements in miles per gallon.
- Enhanced Engine Sound: This is perhaps the most noticeable benefit for many enthusiasts. A performance exhaust system can transform your vehicle's mundane hum into a deep, resonant growl or a high-pitched scream, depending on the system and your preference. The sound is meticulously engineered to provide an engaging auditory experience.
- Weight Reduction: Many aftermarket exhaust systems are constructed from lighter materials like stainless steel or even titanium, which can significantly reduce the overall weight of the vehicle compared to heavier stock components. This weight saving contributes to better handling, braking, and acceleration.
- Aesthetic Appeal: Beyond performance and sound, a well-designed aftermarket exhaust system with polished tips and a refined finish can dramatically enhance the visual appeal of your vehicle's rear end, giving it a more aggressive or sporty look.
The specialists at Mij Exhausts understand these nuances and can advise on the ideal system to match your specific vehicle, driving style, and desired outcomes, ensuring you achieve the perfect balance of power, sound, and aesthetics.

Maintaining Your Performance Exhaust System
Once you've invested in a high-performance exhaust system, a little care can go a long way in preserving its condition and performance. While stainless steel systems are highly resistant to corrosion, regular cleaning can prevent build-up and maintain their aesthetic appeal. Avoid harsh chemicals and opt for dedicated metal polishes for the tips. Periodically inspect the system for any signs of damage, loose hangers, or leaks, especially after driving over rough terrain. Addressing minor issues promptly can prevent them from escalating into more significant and costly repairs. Mij Exhausts can also provide advice on long-term care and offer inspection services to ensure your system remains in top condition.
Frequently Asked Questions About Exhaust Systems
How long does it take to install a custom exhaust system?
The installation time for a custom exhaust system can vary depending on the complexity of the vehicle and the specific system being installed. Simple bolt-on systems might take a few hours, while more intricate custom fabrications or full turbo-back systems could take a full day or even longer. It's always best to get an estimate from Mij Exhausts based on your specific vehicle and chosen system.
Will a custom exhaust system void my car's warranty?
In the UK, generally, an aftermarket exhaust system will not void your entire car warranty. However, if a problem arises with a component that can be directly attributed to the exhaust installation or the exhaust itself, then that specific part of the warranty might be affected. It's always recommended to check with your car manufacturer or dealership for their specific policy. Mij Exhausts uses high-quality parts and professional installation techniques to minimise any potential issues.
Are custom exhausts legal in the UK?
Yes, custom exhausts are legal in the UK, provided they comply with noise regulations and emissions standards. The exhaust must not be excessively loud or cause a nuisance. Reputable brands and installers like Mij Exhausts ensure their systems meet all necessary legal requirements, offering a balance of performance and compliance.
What's the difference between a cat-back and a full exhaust system?
A 'cat-back' exhaust system replaces everything from the catalytic converter(s) back to the tailpipe. It's a popular choice as it offers significant sound and performance improvements without altering the vehicle's emission control devices. A 'full' or 'turbo-back' system replaces the entire exhaust from the turbocharger (or manifold on naturally aspirated cars) back, including the downpipe and sometimes even replacing the catalytic converter with a sports cat or de-cat pipe. Full systems offer maximum performance gains but may require an ECU tune and careful consideration of emission regulations.
How do I know if my exhaust needs replacing?
Common signs that your exhaust system may need attention include louder than usual engine noise, rattling sounds (often due to loose hangers or internal muffler damage), a strong smell of exhaust fumes inside the cabin, decreased fuel efficiency, or visible rust and holes in the pipes or muffler. If you notice any of these symptoms, it's advisable to have your exhaust inspected by professionals like Mij Exhausts.
Do I need an ECU tune after installing a new exhaust?
For most cat-back exhaust systems, an ECU tune isn't strictly necessary, as the car's existing engine management system can usually adapt. However, for full exhaust systems, especially those that include a high-flow catalytic converter or a de-cat pipe, an ECU re-tune (or remap) is highly recommended, and often essential. This ensures the engine's air-fuel ratio is optimised for the increased exhaust flow, preventing warning lights, maximising performance gains, and ensuring the engine runs safely and efficiently.
