Lexus RC F RCF Custom Exhaust Options

Reaction score
I am looking for an exhaust setup that increases my horsepower and generally makes the car louder. I will likely add a separate switch to toggle between closed and open (quiet and loud respectively). I love the Meistershaft (45+ HP upgrade claim?? wow...) and the Novel but pricing is around $7,000 - $9,000 and I am more in the $2,500 - $3,500 range where the borla and apexi nx-1 are.

Any other recommendations south of $5,000? What am I missing that is out there? Thank you in advance!
