    Classic sports car tone, mellow and NO DRONE

    Jag E and X type feline British big six noises; purrs at idle, growls under load. Nice burble under deceleration. Just loud enough inside the car to communicate what the motor is doing. Tottaly passes the “wife test”. She hopped into the Stang and we went to eat. When she got out from behind the wheel she was all smiles !Install on my 17 V6 6-speed by Smith Bros. in N.Ky. Driver side took some torch and hangar tweaking. Exactly the classic sophisticated sports car sound I was looking for !
