Hey Guys!
Glad to see so many users are enjoying their ARK GRiP exhaust system! From our personal experience with the competitors' Stinger systems and user reviews, we can confidently say we produce the least amount of drone for the Stinger out of the exhaust systems that actually increase the volume/note.
Exhaust 101 - the only way to increase flow is to either delete obstruction, like a cat/resonator and/or increase the diameter of the piping so that more exhaust fumes can flow out faster. This has to be done without deleting the necessary back pressure but that's for another post.
With that being said, the more room air has to move around the more vibrations the air can make. We combat this in two ways. Helmholtz canisters can fill in at lower exit speeds increasing the travel those fumes need to escape and thus reducing drone. Secondly, a thick steel to reduce the amount of vibration that can escape into the cabin. The thicker the walls of the piping the less the vibration is felt in the cabin. There is a reason why stock exhausts produce hardly any drone. They are heavy (thick) and they are smaller in diameter.
Lastly, we've built headers, downpipes, and test pipes for a lot of vehicles and although power and torque will increase, you will absolutely experience an increase in loudness, raspiness, and especially drone. We're mentioning this for those considering deleting cats and so forth.
The amount of acceptable drone is 100% subjective. The drone can be too loud for some and for others the same volume of the drone is tolerable but the pitch of the drone is wrong for them. We will always try to minimize the drone to a small RPM range without sacrificing the power increase. Drone is part of the package because of the type of upgrade you're going for. The only way to eliminate drone is to keep it relatively close to stock and then we ask ourselves...what's the point?
Here at ARK, we like to focus on three things. How does it sound from the outside? We like a deep growl through the lower RPMs and an increase in pitch during WOT. How does it sound from the inside? Is the drone in the smallest RPM range possible? And lastly, are we increasing the performance of the vehicle? If we are satisfied with those areas then we move on to production.
We are here if you have any further questions about our GRiP exhaust system for the Kia Stinger.
Thank you all!

, however to my astonishment she said the exhaust was good and much better than any other of the other incarnations I've had on other vehicles. When I demonstrated drone at 1500 revs she said it was minimal. Phew that's a relief.
, and my car was the only "stock" car (I did only did the exhaust).
