Installation Notes and Tips

Verify the vehicle’s emissions configuration before ordering. This converter is for Federal / EPA direct-fit undercar use and is not approved for CA emissions vehicles in CA, CO, ME, or NY. Confirm rear-position fitment, inlet style, outlet style, and overall length against the original exhaust assembly before installation. Because the unit uses welded connections, proper exhaust alignment is important for a secure seal and correct fit.
