So I had an ARK GRiiP Exhaust and Z1 HFC’s installed by AWD Tuning and had the car tuned. Seemed to run fine for about 2 weeks and if I attached the link correctly you can hear that annoying noise of what sounds like a Cicada stuck in the pipe. What’s odd is: on the lift, the noise happens after letting off the throttle, when driving, it happens when accelerating at high rpms.
If anyone has any ideas - the guys at AWD Tuning are a bit stumped as well.
