As per my post on another thread:

As for the exhaust tips...Lexus has already made a statement that this setup aids in exhaust flow, creating a scavenging effect. So it's not a "gimmick" as it actually serves an engineering and performance purpose.

The IS-F, M3, C63 and RS4 are ALL great cars, they all have their pros/cons and will all make a buyer happy. Thanks for the great review...as an IS-F owner, I had a great review of the M3...
