I dunno about 'em but my muffler shop here was even surprised that it didn't sound like a bumble bee at all and was happy of the turn out because they tried to discourage me about replacing it at first. I love the sound of it that I let my boss drive it at lunch break most of the time just to let me hear how it sounds outside and it's just greaaaaatttt! No mosquito sound bytes at all!

If you'll gonna have Borla...keep your stock because Borla is still restricted in airflow with the same loop design from the stock.
