I special ordered a 2021 GT Premium with active exhaust but the shut downs for microchips and gas leak wore my patience. So I found a 2021 GT California Special I am buying tomorrow and put the down payment down already. I get that a lot of Mustang people love the loud sound but I don’t prefer it so loud (test drove it). This GT Cali Spec doesn’t come with active exhaust. What would be the best quiet exhaust to replace the stock with, without gouging my wallet? The Rousch active exhaust is almost $3k!!! That’s crazy! Gotta have my Mustang but need it a little quieter. Any help will be much appreciated.
