Pro Tip Check state laws for CARB compliance. Bolts WILL be seized.
🚗 Vehicle-Specific Notes
Honda
California models need CARB-compliant cat. Check state emissions requirements.
Toyota
Very common theft target due to high precious metal content. Bolt-on or weld.
Ford
Bolt-on with gaskets on most. Studs may break — penetrant 24hrs before.
Subaru
Close-coupled to header. May need to replace as header-cat assembly.
BMW
Multiple cats (pre-cat + main cat). Check both. OEM is expensive — check for CARB-compliant aftermarket.
