Before you buy
Questions people ask
If your car is not in the list, or you are not sure which part you need, tell us the model, the engine code and the year.
Ask us about your carWill this fit my car?
Pick your car at the top of the page and the site tells you whether this part is listed for it. Fitment goes by engine and chassis, not by year alone: two cars of the same year can take different parts. If your exact car is not in the list, message us with the model, the engine code and the year before you order.
Do I need a tune after fitting this?
For catless downpipes, yes. Removing the factory catalytic converters sets a check engine light that only a calibration clears. For intakes and adapters a tune is not required, but it is how you get the most out of the part. Budget for it with your installer before the part arrives.
Is it plug and play, or does it need a workshop?
Parts are designed to bolt on to the factory mounting points with no cutting and no modification. That said, downpipes and turbo parts are a workshop job: they sit under the car, under load and under heat. Installation guides are published on the site for the parts that have one.
How long does it take to arrive?
It depends on where the part is. Parts held in the United States ship in 3 to 5 business days after 1 to 3 days of processing. Drop shipped parts come directly from our manufacturer and typically take 5 to 7 days to arrive; no expedited shipping is possible, and import tariffs and duties are the responsibility of the customer. Each product page says which one applies. Intakes and downpipes ship with signature required.
Can I return it if I change my mind?
Within 30 days, if it has not been installed and the packaging is intact. A restocking fee applies. Once a part has been installed, or installation has been attempted, it cannot be returned. That is why we would rather you check fitment with us first than guess.
Is this street legal?
Catless downpipes are not. They replace the factory catalytic converters and are sold for closed-course and off-road use only. Emissions rules are set federally and by your state, and it is on you to check what is permitted where you drive. Intakes, adapters and filters are not affected.
