I first had stock exhaust and I removed the resanator and I replaced the stock resonator to 2 smaller resonators and that sounded good but it was a mistake, After I replaced the stock mufflers with Dinan Free Flow Exhaust I still had the 2 small resonators on the exhaust and it was way to loud! So I removed the resonator and replaced it with the Magaflow X-Pipe the sound and performance were day and night difference. The sound was absolutely superfluous and what I've been trying to achieve from the beginning. This is the best investment I've made on the car for the exhaust hands down. If you have a BMW X5 and you'd like to improve the sound and achieve the growl,buy a Magnaflow X-Pipe and you'll be happy.
