⚠️ Crucial Steering Rack & Transmission Compatibility Warnings:
1. Steering Rack Restriction: This product (Part No. A228SS) is engineered strictly to clear standard power steering setups. Because of the specialized housing dimensions required by electronic variable-effort steering systems, this header assembly will NOT fit models equipped with a Variable Speed Steering Rack (variatronic steering setups found on select premium Calais or Statesman variants).
2. Manual Transmission Fitment: This base model is designed for automatic transmission configurations and will NOT fit clutch cable manual models due to mechanical space constraints. If your vehicle uses a hydraulic manual transmission layout, you must use part number A228M (Mild Steel) instead to guarantee clear routing lines around the slave cylinder.

Please Note: Professional installation by an exhaust specialist or qualified automotive mechanic is highly recommended to guarantee proper system alignment and a perfect leak-free seal.
