I absolutely love the hiss. I do not even know why people do not like the hiss. However the ART's are causing annoying rasp/rattle. I would like to see if my ART's will cause the same on the ARK.
If the DTS is too silent, Ill go the HFC route anyway (FI
)
Some questions for you though.
When the car is idle, Does it have a (best description) rumble ?
Butt dyno any different ?
Turbo Compatible ? ( Some exhausts are too restrictive for turbo or so i understand)
