    Alright, I have the Aero 2525 and I love it to death but have one slight issue. I have this little rasp that pops up between about 2300-3000 RPM and it pisses me off and the DTLTs that I plan to order soon will just accentuate it. Also, I carry passengers often and people in the back seat cannot hear up front haha. I am looking to get a resonator but don't know what length to get? Can someone explain to me what different lengths in a resonator does as well as examples? I already know that different lengths cancel different sounds, but I have no idea the sound difference between a 13" or like a 17" resonator sitting in an exhaust system. Any help is appreciated. Thanks
