When my package arrived i already had the old exhaust out, it was no problem at all since my car is 2018...didn't even need to use PB. The install was easy as well and the fit of the FI was just perfect. What i didn't expect is the loudness
Not even sure if it should be so loud or if i should check for leaks. You can hear the car half mile away just normal driving and probably from much further away when stepping on it. I love the sound it makes but i can't imagine how one without the resonators would sound lol since 12" is this loud. I am on Berk HFC. The car sounds now so much faster than it really is
