You need to check out all the options and sound clips for an exhaust system before buying. Some are known to have drone and interior noise and some don't. Most of the systems are made of stainless steel so you will never have to worry about rusting. Most of the systems have various sound levels and tip options to choose from. Some of the best quality, best sounding and all around best systems made for your Challenger Hellcat come from Borla, the Borla ATAK is aggressive, loud and will get you and your Hellcat noticed. A very similar system is the Corsa Extreme, this is loud and aggressive as well.
