• Currently made to order with an estimated 12 weeks from the time order is placed until it ships. We nor SDP cannot guarantee the time frames as there are some elements out of our hands that get passed down to SDP from certain suppliers on the material. 
• For an emissions-compliant setup, your factory Oxidizer/downpipe must be sent in so that SDP can modify it to work with the factory exhaust or there will be a charge of  $450 for a new unit for SDP to start with. SDP modifies it to allow it to fit in the compound turbo application and stay emissions compliant. It will also be Ceramic coated with the hot parts which will greatly help with keeping the heat in the exhaust.
