LS3 normally make an exhaust popping and gurling sound during deceleration and the sound becomes even more noticeable and louder with an exhaust mod. I happen to like the noise but others find it annoying. The popping is caused by the DFCO (deceleration fuel cut off) and is a stock feature of the LS3 (maybe L99 as well?). Other than for sound suppresion, what are the benefits of tuning out the popping?
