Boost Logics 3″ Downpipe Kit is a quick and easy install for any BPU Car or even upgraded stock frame turbochargers that are found in our 750 Package. These Stainless Steel Downpipes offer superior airflow and heat management over the OEM design. Thick one piece cast flanges not only resist warping, but can hold up to the toughest abuse that would normally crack a thinner OEM design. By replacing the restrictive OEM parts with 3″ mandrel bent tubing these downpipes not only increase performance, but also dramatically increase the definition and tone of the exhaust. All our downpipes come ceramic coated to help keep the heat inside the piping, helping to reduce engine bay temperatures and improve exhaust velocity. These downpipes come with all necessary hardware & gaskets needed for install . DISCLAIMER : This product is for “off-road use only”– check your local laws & regulations regarding the modification of the exhaust system by checking the vehicle code for your state. Many states are stringent on exhaust modification laws to pass SMOG.
