The next improvement after  adding power with software is an intake is Exhaust. As well as helping air move through your engine this also adds an excellent ecstatic and more aggressive sound. Original equipment exhausts are designed to be quiet and cheap to produce but often don’t do a lot to add to your car. We carry many companies but two of our favorites are Milltek Sport and AWE Tuning. Both companies offer excellent quality and mastery of the engines they design for to get the most of your car. AWE Tuning is American made in Pennsylvania. With every exhaust they design they spend extensive time with the exhaust in an acoustic chamber to find the best sound
