If you already heave headers installed and drone is a concern you have then I would recommend going with one of the
Corsa Axle back options. They advertise their system help eliminate drone and I had a Customer in the past who ended up swapping out his axle back exhaust for a Corsa one which solved his drone concerns he had when his headers were installed.
If drone isn't a concern for you and you still want a performance increase at a better price then one of the
MBRP systems could be a good choice.
