    Rated 4 out of 5 by from Outstanding Sound! Having no experience with this product, I decided on this Dynomax for my Chevy 8.1L 2500HD daily driver with the hopes that it would have a muted, yet aggressive sound which is exactly what this muffler provides. This Dynomax provides a nice tone at idle that won't annoy the neighbors during early morning warm ups. Under acceleration this muffler emits a very clean an aggressive note, but once at speed and in overdrive it settles down nicely to a manageable cruising tone. Interior droning is noticeable between 1800-2200 rpm, but again manageable (my wife doesn't even complain). Cruising with music playing and holding a conversation is possible, but crack the throttle into a downshift and everyone around will know you intend to pass. If you're looking for the baddest, loudest muffler on the block this is not for you. If you are looking for a more adult, clean sound with no popping or backfire this is definitely what you're looking for.
