ISR Performance Exhaust Y-Pipe | Nissan 370Z, Infiniti G37/Q60

Makes the exhaust have a more deeper tone when starting the car and being in the 2k rpm, also making like a deep rasping sound when slowing down without the brake from around 3k rpm to 2k rpm. Reaching 3k rpm creates the famous VQ trumpet noice and stops at around 3,4k and then creating the noice again when reaching 5k rpm. Love it really, all based on personal experiences.

Great product
