There was a thread some time back on test pipes and sound. Some guy actually measured the sound of his exhaust before and after test pipes. The sound level went up some but not much. My personal impression is with test pipes the sound is a little louder and raspier under hard acceleration but not really different when just cruising around town. Good luck !
