Help with Powershell export to CSV

Hi,

Any Idea how to improve that and make it faster maybe?

$servers = Get-ADComputer -SearchBase 'OU=Sites,DC=domain,DC=com' -Filter '*' | Select -Exp Name
foreach ($line in $servers)
    {
        Get-WmiObject Win32_Service -Computer $line -filter "STARTNAME LIKE '%XYZ%' OR STARTNAME LIKE '%ABC%'" | select Name,DisplayName,StartMode,State,StartName,PSComputername | Export-Csv C:\DIR\DIR1\Report.csv -NoTypeInformation -Append}
        

thanks a lot!
