I installed the Switchfire on my 2019 Mustang GT premium PP1 with active exhaust. The sound during exeleration was absolutely a beautiful race car full sound. I have to say I was amazed at not only how it sounded but how I feel my car power band was improved. I really never expected the results I got from just a resonator delete pipe. Worth the money.
