If you are running a muffler that is known to drone, you might consider the test pipes with resonators. I ran the the cheap eBay test pipes (no resonators) and eBay muffler, and I had no droning what do ever. If you running a stock muf, skip the resonators. If you are running something like a GLH muffler that is known to drone, I would consider the test pipes with the resonators.
