Any good exhaust shop that can customize a Fabspeed Supercup with Helmholtz resonator
As the title suggests I am curious if anyone has a recommendation for an exhaust shop in the N. Atlanta area that can do the math to customize the Fabspeed Supercup exhaust to remove (or greatly reduce) the drone. They would need to have experience doing this and be good with maths. Lmk what you got.
