I could try with my cellphone??? Probably would suck though.
Put is this way, with just the magnaflow there wasnt much noise in the cab except when you into the throttle for the most part.....the noise I heard was pleasant.....with the catless pipes, you hear everything, even in sixth gear.......those pipes really bring out a low end tone. Some people might not like the sound in the cab but I dig it.
All my neighbors heard me leave at 7 am the other morning!!
