I was wondering if anyone has added resonators to quiet down their aftermarket exhaust systems. I've had my FI exhaust and Berks HFC for close to a year now, though it's quiet enough for me on the outside, the inside of the car has incessant vibrating issues because of it. It's louder when I have the windows closed than when i have them open. Any ideas? I've read a little about someone adding the resonator modules from the XYZ test pipes to another aftermarket system, but I wouldn't know how that works.

are you talking about the drones?
if it is, that is the main reason why i got rid of my f.i.

 

you can most definitely add resonators to your setup. but why hack up such an expensive kit, naah mean? (cut current and add heftier magnaflows, for example). i hear they're not drone eliminating mechanisms on the market at the moment...i've heard good things about them (don't recall specific brand however).
