Construction All Sheepey Built headers are hand constructed in Southern California by fabricators with decades of experience. Sheepey Built uses high quality stainless steel, slip joint merge collectors, and CNC head flanges. We also use high quality stainless steel flex bellows instead of the typical braided flex couplings that quickly get beat up and leak.

All of our turbo manifolds maintain a 10 year warranty to the original owner from the purchasing date. Our warranty covers all material and manufacturing defects. All of our fabrication is done in house in the USA. We utilize the best material and fabricator available to ensure that you'll never have a problem. We do NOT cover warranty claims on issues caused by you. We also do not warranty second hand owners at this time.

It is illegal to install an aftermarket part that alters or modifies the original design or performance of the motor vehicle pollution control system unless the part has an executive order from CARB. Installation of parts which are not CARB-approved on a pollution controlled vehicle in the state of California may result in the DMV revoking the vehicle registration and title, refusing the transfer of registration, and/or the vehicle failing smog inspection. Law enforcement may cite you for the use of an illegal aftermarket part and seize your title and license plate.
