I have a 2010 GT, with Corsa Sport axle back. Absolutely no drone anywhere and great aggressive sound. Highly recommended despite the price.

This. They are like 800 bucks or something like that but I've read several reviews that state the same thing.

Removing the cats is when you open your exhaust tone up for drone and trumpeting. Some sites like AM have a chart showing how loud a item is over stock. Dont forget everytime you change something it will effect the tone. If you really are concerned about drone just buy a conservative muffler and you'll be fine.

FRPP KR. They are much louder than stock and have no drone. I had GTAs, Stingers, LMs, and the FRPP sound the best to me, even after a couple of years.
