Performance exhaust systems & fitting in Slough

A performance exhaust is an aftermarket exhaust system or component designed for a particular vehicle. Products vary in construction, materials, configuration, sound characteristics and intended use.

A cat-back exhaust generally replaces the relevant exhaust sections behind the catalytic-converter area, although the exact components vary between vehicles and products.

An axle-back exhaust generally replaces part of the rear exhaust arrangement. The sections included depend on the vehicle and manufacturer.

A resonated system contains a resonator in the relevant configuration, while a non-resonated variant omits that component. Sound characteristics vary by engine and product, and neither configuration should automatically be assumed suitable for road use.

A valved exhaust uses valves to change how exhaust gases travel through the system. Depending on the design, different valve positions can affect sound characteristics. Compatibility and permitted operating modes depend on the vehicle and product.

Some systems may change the exhaust sound, but the result depends on the vehicle, product and configuration. An aftermarket exhaust must still meet applicable road-use noise requirements.

Genuine product-specific sound examples may be available from the manufacturer or verified vehicle recordings. The sound of your own vehicle may differ because of engine, configuration and recording conditions.

Available manufacturers depend on current supplier arrangements and the exact vehicle. STX Tuning can check suitable genuine exhaust products when you provide your registration and requirements.

STX Tuning can discuss suitable cat-back exhaust supply and fitting at the Slough workshop. Product compatibility, intended use and installation pricing must be confirmed.

Customer-supplied exhaust systems may be considered for fitting after checking the vehicle, product reference, suitability and installation requirements. Contact STX Tuning before booking.

Pricing varies by manufacturer, vehicle, exhaust design and components included. A complete cat-back or valved system may have different costs from a rear silencer upgrade. Request a vehicle-specific quotation.

Installation prices depend on the vehicle, product, access required and any additional components. Send us the registration and exhaust details for a quotation.

Fitting time depends on the vehicle and system. Some installations are straightforward, while others involve more components or access requirements. We'll confirm the appropriate appointment arrangements when quoting.

Road-use suitability depends on the exact product, vehicle and applicable noise and emissions requirements. A non-resonated system should not be assumed legal or illegal solely from its name.

That depends on the product, installation and operation. A valved system isn't automatically lawful in every mode. The relevant approval and noise requirements must be checked.

Required emissions-control equipment must be retained and remain functional on road-going vehicles. A performance exhaust enquiry does not automatically include catalytic-converter removal.

Removing a resonator can change exhaust noise and may make the system unsuitable for road use. The vehicle's applicable noise requirements and the proposed modification must be considered before work is offered.

Some compatible cat-back systems are designed to retain the vehicle's existing upstream emissions equipment. Confirm the exact product and vehicle arrangement before ordering.

An exhaust modification does not guarantee additional horsepower. The effect depends on the vehicle, system design and overall setup. Any specific performance claim should be supported by relevant evidence.

Not always. Some compatible cat-back exhausts can be fitted without separate ECU tuning. Software suitability depends on the vehicle and the actual components changed.

You can enquire about a suitable exhaust and Stage 1 ECU remap together. Hardware compatibility and the ECU calibration must be appropriate for the actual vehicle.

There is no universal Stage 2 hardware requirement that applies to every engine. Supporting parts should be selected according to the exact vehicle and an appropriate calibration, while required emissions-control equipment must remain in place for road use.

Some exhaust designs may produce noticeable sound at particular engine speeds. The effect depends on the engine and system. Resonator and silencer designs can influence the sound characteristics.

Stainless steel is commonly used in aftermarket exhaust construction for its corrosion resistance and appearance. The overall quality and suitability depend on the grade, design, manufacturing and application.

Some vehicles have suitable tailpipe or rear-section options. Whether a particular finish or configuration fits depends on the existing exhaust, bumper and diffuser.

Certain vehicles may have compatible quad-exit exhaust products, but the rear bumper, diffuser and installation requirements must be checked. A quad-exit conversion should not be assumed available for every model.

An aftermarket exhaust is a vehicle modification and should be disclosed to your insurer. Your insurer can explain any effect on cover, conditions or premium.

Aftermarket exhaust modifications may affect manufacturer warranty claims, particularly those connected to modified systems. The outcome depends on the vehicle and warranty terms.

Suitable exhaust systems may be available for selected BMW, Audi and Volkswagen models. The correct product depends on the exact engine, generation, exhaust configuration and body style.

STX Tuning can review a customer enquiry involving a particular manufacturer and product. Supply availability, fitting acceptance and vehicle compatibility must be confirmed before an appointment.

Excessive exhaust noise and missing or defective emissions-control equipment can cause inspection issues. An MOT pass does not automatically establish that every exhaust modification is lawful for road use.
