How long does shipping take?

In-stock orders ship in 3-5 business days. Orders are inspected and packed by our team before they leave our Oceanside facility. Made-to-order lead times are listed on the product page. Tracking is emailed as soon as it ships.

On backorders: if something you ordered is out of stock, we tell you quickly, with a realistic timeline. You can wait it out or cancel before it ships. Either way you hear from us, not silence.

Do you ship internationally?

Yes, worldwide. We have shipped to customers across North America, Europe, Asia, and beyond. International orders take longer due to customs and prep. Email support@cencalmotorsport.com for an accurate lead time before ordering. Duties and import fees are the buyer's responsibility.

How do I track my order?

Tracking is emailed automatically when your order ships. Check anytime on our Order Status page. Need help? Email us your order number and we will pull it up.

Can I cancel or change my order?

Email us as soon as you can with your order number. If it has not entered production or shipped, we will do our best. Made-to-order items cannot be cancelled once production starts. Nothing cancels after it ships. Full details: Cancellation Policy.

What is your return policy?

• Damaged, lost, or stolen in shipping? That is what Package Protection is for. File a claim and we will get it moving.
• Manufacturing defect or fitment issue? Send us photos and we will work through it under our Warranty Policy.
• Made-to-order items (most wheels, most exhausts, custom-spec parts) are not returnable.
• Eligible standard items can be returned within 10 days of delivery. A 20% restocking fee applies, or choose store credit. See the Return Policy.

To start a return: email support@cencalmotorsport.com with your order number, item, and reason.

Got the wrong item?

If we shipped the wrong item, reach out and we will make it right. If you ordered the wrong fitment, we can look at an exchange on a per-order basis. Full process: Exchange Policy.

What if my part is defective?

Email us as soon as you can with your order number and clear photos or video of the issue, and do not install a part you think is defective. We will take a look and work through it with you under our 90-day Warranty.

How do I know if a part fits?

Compatible chassis are listed on every product page. Not sure? Email us your year, make, model, and chassis code (G80, F82, A90, etc.) before ordering. We have answered this question thousands of times. Better to ask first.

Do you guarantee fitment?

Every part we list is verified against the chassis shown. We check fitment on our own cars across BMW, Supra, Porsche, and exotic platforms before we sell it.

Our fitment guarantee, like our warranty, applies to professional installation at a shop. Proper installation is how fitment gets confirmed; a part that is forced or installed incorrectly can read as a fitment problem when it is not. If a part does not fit as listed on a professional install, stop, document it with photos and video, and contact us before going further. We will make it right.

Which platforms?

BMW: E46 M3, E9X M3, F8X M3/M4/M2C, G8X M2/M3/M4, F90 M5, F-series M8, M340i/M440i, B58 and N-series.
Supra: A90/A91.
Porsche: 911, GT3, GT4 RS, Cayman, Panamera, Cayenne, Macan, and more.
McLaren and select exotics.
Most systems available in stainless or titanium, configured to order. We test-fit these systems on our cars and back them with our support, drawing on years with these platforms on the street and on the track.

Valved vs. Race

Valved: electronic valves switch between a quiet street mode and fully open. Quiet when you want it, loud when you do not.

Race (non-valved): straight-through, fully open at all times. Maximum sound and flow, with no valve to close.

Valve Control Options

• Full active valve systems with electronic actuation
• Full weighted wireless remote included on supported systems
• OEM valve integration on certain models, running off your factory exhaust controls and drive modes. Email us to confirm your model.

Wet Carbon

Carbon fabric laid by hand into a mold, saturated with resin, and cured at room temperature or with light heat and vacuum. Slightly heavier than dry carbon, with minor weave variation piece to piece. Most cost-effective. Standard for most cosmetic aero.

Dry Carbon (Pre-Preg)

Fabric pre-impregnated with a precise resin ratio, vacuum-bagged, and autoclave-cured under heat and pressure. Lighter, stiffer, and more consistent weave than wet carbon. More labor and equipment intensive. Costs more.
