Leave your VIN at checkout to confirm exact fitment before fulfillment. If no VIN is provided, we'll contact you by email before your order moves into production — this step exists specifically to avoid mismatched fitment on a part this involved to install.
Installation
The downpipe ships as separate sections that require assembly during installation. Factory sensor locations are retained, so no relocation or deletion of OEM sensors is needed. Professional installation is recommended given the complexity of a full downpipe swap.
Production & Shipping
Production time is typically 15–20 business days after order placement. Shipping cost varies by location, generally $135–$275 USD worldwide, with final method (air or sea freight) and cost confirmed after your order is placed.
