Hey, I've got a 2.5" cat back exhaust on my XF, however I find it to be too loud and too droney. There's only 1 muffler which is located before the diff, it's an auspac one, similar to the standard muffler, but larger. I want to quieten down the exhaust a BIT, but I'd still like the car to be fairly loud, and have a bit of a note, just needs to be a bit quieter, Where would be the best spot to add another muffler? up the front near the cat, or down back somewhere in the tailpipe? What sort of mufflers would u guys suggest?
