Fitment

Not sure a part fits? Before you order, send your year, model, engine (B58 / S55 / S58) and VIN through the contact page. We'll confirm fitment.

Orders

Your tracking number is emailed as soon as it's available. Problem with an order? Use the contact page and include your order number.

Shipping

Processing times, rates and tracking: see shipping.

Returns

30 days on unused, uninstalled parts. Start with the returns policy.

Warranty

12 months against manufacturing defects. See warranty.

Installation and tuning

We recommend professional installation. Catless downpipes need a tune, high-flow catted downpipes run best with one, and intakes and charge pipes don't need one.

Emissions

Some parts are sold for off-road / competition use only. Read the off-road use policy before you buy one.
