So I've been wanting to do a custom exhaust on my jetta for a while and i'm finally going to do it. I am going to fab up a 3" exhaust for my 2.0t that will be partially side exit but will turn down to be hidden. The rear bumper cutout is getting shaved, smoothed, and painted. I haven't decided what muffler to use yet. I'm looking at a Borla XR-1 racing muffler or a Magnaflow muffler. I was also considering a Flowmaster, but really don't like how loud they are. Right now im running a TT with Borla and love the sound. What muffler would be good for my use? Good performance, but not extremely loud?
