There's no drone at all and making better sound + performance 20whp gain + no cell since I drove my car for 2k miles ( some people said it pops the engine cheek light, but mine doesn't ) You'll love the Fabspeed pack + stock exhaust system if you are fan of the stock exhaust. I hope you make a right choice!

Your car sounds amazing!

It's a great sound even with the use of the stock mufflers. Absolutely aggressive!

On the aftermarket X-pipes, you can choose to run a cat bypass pipe or a set of sport catalysts. The OEM pipe does contain it on one unit, but with the aftermarket options you can play with it a bit in terms of setup.
