FJ MotorWerkes | Frequently Asked Questions
Find answers to our most frequently asked questions about products, orders, delivery, warranties, installation and aftersales support.
1. Are all your products kept in stock?
Not all products are held in stock. We prioritise our fastest-selling products for immediate availability, while offering some of the fastest production turnaround times in the UK performance aftermarket.
2. My delivery hasn’t arrived. What should I do?
Tracking information is provided with every dispatched order. You can contact the courier directly or ask our team to raise an investigation on your behalf.
Courier investigations typically take 48–72 hours for an initial response. Contacting the courier directly may provide a quicker update.
3. What does your lifetime warranty cover on exhaust systems, midpipes and decats?
Our lifetime warranty covers manufacturing welds and structural integrity for the duration of your ownership.
Damage caused by accidents, incorrect installation, misuse or external factors is excluded. Proof of purchase may be required.
4. What warranty do you offer on fully forged wheels?
Our fully forged wheels are covered against structural deformation resulting from manufacturing defects.
Our wheels are engineered for demanding fast-road and suitable track applications. Damage caused by potholes, collisions, road hazards or accidental impact is not covered.
5. Can I pay extra to receive my order faster?
Expedited shipping may be available at an additional cost, but production lead times cannot be expedited through additional payment.
Estimated delivery times after dispatch:
- United Kingdom: 1–3 working days
- Europe: 3–5 working days
- USA & Canada: 5–8 working days
- Rest of the World: 8–14 working days
Where applicable, our team will confirm estimated production and dispatch lead times following purchase. Delivery estimates exclude production time and customs delays.
6. Can I cancel or refund a custom-made order?
Custom-made orders can generally be cancelled before production begins.
Once manufacturing has commenced, change-of-mind cancellations and refunds are not accepted, as the product is being manufactured to your specifications.
7. Can I cancel my software order?
Software orders may be cancelled before the licence, activation key or digital product has been supplied or activated.
Once supplied or activated, cancellation eligibility depends on the applicable software terms.
8. Will your products or software affect my manufacturer’s warranty?
We recommend consulting your warranty provider before modifying your vehicle.
FJ MotorWerkes cannot guarantee manufacturer warranty coverage or complete software undetectability. Modifications that are not visible through basic diagnostics may still be identified during advanced manufacturer investigations.
9. I’ve ordered a product but also require fitting. What should I do?
Simply add “Fitting Required” to your order notes. Our team will contact you using your supplied telephone number or email address to discuss installation arrangements.
10. Why am I charged delivery when my exhaust is being fitted by one of your installers?
FJ MotorWerkes is primarily an online performance parts supplier. Shipping charges cover transportation to your address or directly to your chosen installer.
We frequently deliver directly to installation partners for your convenience.
11. My order has been delayed. Am I entitled to compensation or a discount?
We do not automatically provide goodwill discounts or compensation for delays caused by couriers, customs or other circumstances outside our control.
Our team will assist in resolving delivery issues as efficiently as possible.
12. What is your policy on abusive or inappropriate communication?
We expect mutual respect in all customer interactions.
Threatening, abusive or persistently offensive communication will not be tolerated. We reserve the right to end conversations or restrict communication to written correspondence where necessary.
13. Why do your exhaust systems look different across product photographs?
Our exhaust systems are available in multiple configurations, including resonated or non-resonated designs, H-pipes, X-pipes, valve arrangements and exhaust tip options.
Appearance and sound vary depending on the selected specification.
Product images are for illustration purposes only. Your system will be manufactured to your agreed configuration.
Product Compatibility & Installation
14. How do I know if your product will fit my vehicle?
Contact our team with your vehicle registration, model, year or VIN. We’ll help verify compatibility and recommend the appropriate product.
15. Do your exhaust systems require cutting or welding to install?
Our midpipes generally require one cut before the factory rear muffler. Supplied clamps allow the original exhaust configuration to be reinstated.
Our catback systems are designed as direct bolt-on replacements, requiring no cutting where specified.
16. Can I purchase your products without using your recommended installers?
Absolutely. You’re welcome to use your preferred installer.
We recommend experienced performance specialists and can also arrange fitting through our installation partners.
Forged Wheels & Custom Manufacturing
17. Can you manufacture forged wheels to my exact specifications?
Yes. Our fully forged wheels can be manufactured to your required diameter, width, offset, finish and colour.
Our team can also advise on suitable vehicle-specific fitments.
18. Can I return custom-forged wheels if I don’t like the colour or fitment?
No. Custom-forged wheels are manufactured to your agreed dimensions, finishes and specifications.
Once production begins, exchanges or refunds for changes of preference are not accepted. Please confirm all specifications before manufacturing commences.
Software, Modifications & Compliance
19. Is OPF coding reversible?
Yes, where supported by the vehicle and software.
However, reversing modifications does not guarantee that previous software changes cannot be identified through advanced manufacturer diagnostics.
20. Can you guarantee my vehicle will pass an MOT after modifications?
Our performance exhaust systems are supplied for off-road use only.
We cannot guarantee MOT compliance or road legality following modifications. Contact our team for product-specific guidance.
21. Will fitting aftermarket parts affect my insurance?
We recommend declaring all relevant vehicle modifications to your insurer.
Insurance coverage and acceptance of modifications depend on your provider’s individual terms.
Returns, Customer Service & Pricing
22. My product arrived damaged. What should I do?
Please contact our team promptly with photographs of the product and packaging. Avoid installation until the issue has been assessed where possible.
Full procedures are available on our Refunds & Returns page.
23. I’ve fitted my product, but I’m unhappy with the sound. Can I return it?
Custom-made exhaust systems cannot be returned simply because the sound does not meet personal preference.
Sound varies depending on vehicle specification, resonators, pipework and valve configurations. Our team provides guidance before purchase to help you select the most suitable setup.
24. Do you offer discounts if I purchase multiple products?
Our pricing is already highly competitive.
Orders below £3,500 GBP are fixed-price. For larger orders, contact our team to discuss potential package pricing.
25. Do you offer Klarna or Shop Pay Instalments?
Yes. We offer Klarna and Shop Pay Instalments on eligible purchases.
Applications, approvals and repayment arrangements are managed directly by the respective providers, subject to their terms and eligibility requirements.
International Orders, VAT & Customs
26. Will I have to pay customs charges, import duties or VAT on international orders?
International orders may incur import duties, local VAT and customs fees imposed by your destination country.
These charges are payable to the relevant authorities. FJ MotorWerkes does not receive any portion of government-imposed import taxes or duties.
Unless expressly included at checkout, these charges are the customer’s responsibility.
We can provide commercial invoices and supporting documentation for private and business customers where required.
Customs processing times, tax rates and import regulations are outside our control.
Production & Customisation
27. What are your production times and custom-made product lead times?
We supply individual customers alongside tuning garages and trade partners, with bulk orders of 5–50 units occasionally affecting stock availability.
Unlike fixed, off-the-shelf products, our custom-made systems are configured to individual requirements.
Production times depend on the product, specification and current demand. Our team will confirm your configuration and estimated lead time following purchase.
28. Will the price increase following my exhaust or wheels consultation?
No. Your purchase price includes the consultation and available configuration options, with no hidden charges.
For example, our BMW M3 G80 catback systems offer a selection of exhaust tips, muffler designs and valve configurations within the advertised price. The same principle applies to included forged-wheel customisation options.
Additional charges apply only to substantial order changes, such as upgrading materials or changing wheel dimensions.
The price you see is the price you pay for your selected product and its included configurations.
29. What happens if I damage a product during installation?
Damage caused by incorrect installation is the responsibility of the customer or appointed installer. We strongly recommend professional fitting only.
With nearly 10 years of industry experience, we understand our products and their tolerances. Damage such as stripped threads, overtightened clamps or broken bolts often results from improper tools or excessive torque.
