I am new here and am looking for: 1) suggestions for placing quintuple ALP heads (3 front, 2 back) in BMW 2018 M550, 2) great installer in Northwest Ohio / Detroit area. I figure the car is too low for Tx head on the front and wonder about the value of one on the back. The vertical "kidney grill" vents are "active" in that they open and close depending on car speed and engine venting needs and thus heads cannot be placed behind them.

Thanks in advance.Name: Front m550.jpg Views: 1747 Size: 200.1 KBName: BACK M550.jpg Views: 1898 Size: 143.7 KB
