Frequently Asked Questions:
- What is the difference between catless downpipes and catted downpipes
Catless downpipes lack a catalytic converter, allowing for maximum exhaust flow, increased performance, and a louder exhaust note, but they produce more emissions and can trigger a check engine light. Catted downpipes include a high-flow catalytic converter, offering a balance between performance and emissions compliance while producing a slightly quieter exhaust.
- What is the difference between stock catalytic converter and sports catalytic converter?
A stock catalytic converter has a high cell density (typically around 800 cells per square inch), which maximizes emissions reduction but restricts exhaust flow, limiting performance. A 200-cell sports catalytic converter has a lower cell density, allowing for significantly better airflow, increased horsepower. The exact performance gains can vary depending on the vehicle's tune and driving conditions. High quality Stainless Steel construction and special precious metal wash coat delivers consistent emissions reduction, with a significant reduction in size and weight.
- What is OPF/GPF and how do I know if I have it?
OPF (Otto Particulate Filter) / GPF (Gasoline Particulate Filter) is a filtration system installed in modern gasoline engines to reduce fine particulate emissions. It works similarly to a diesel particulate filter (DPF), capturing soot and periodically burning it off. If your car is a post-2019 EU model, it likely has an OPF/GPF. To check if your car has an OPF/GPF, you can ask us via contact form and your Vehicle Identification Number (VIN).
- What payment options are there?
We accept payment by credit or debit cards, PayPal, Apple pay and Google pay. Payment for all orders will be made at the time of checkout. Please note our website does not process your card transaction directly. Your payment will be processed at web-site of payment system. We are committed to protecting your privacy and security.
- When will my order ship?
We aim to dispatch standard in-stock orders within 2-3 business days. Some in-stock items may ship within 1 business day, after which you will receive a tracking number via the email address provided at checkout. This allows you to monitor your shipment's progress.
For certain items, shipping may take longer due to product availability. Orders containing items that are out of stock, custom, or located in our partners warehouse may require additional processing time. If your order is time-sensitive, we encourage you to contact us before placing your order to confirm availability and estimated delivery time.
