What are your plans with the car? I would almost always recommend starting with the headers first. It’ll give you much more volume and power. However, you’ll need a tune, which will void your warranty. So as long as you’re ok with that, that’s the route I’d go. If you’re trying to keep your warranty, then pretty much any axle back system will suffice to make your car louder. Exhaust is extremely subjective so, listen to systems you are interested in online and then try to find someone in person with that setup.
