There is absolutely no drone at all .. even though the system costs more than standard, meaning equal to Corsa .. but a hellava lot better than the cheaper brands of Flowmaster, MagnaFlow, Gibson etc etc .. I'm glad I invested into more than going with the others. Corsa was my second choice, but they do not offer at dual cat-back system.
I picked it up from ALLExhaust.com .. it was the cheapest I could find .. and you'll find that on this site, ALL there exhaust systems are all excellent pricing.
Borla (140173) Stainless Steel Cat-Back System set me back $ 868.55 with free shipping.
