Buy the Borla catback https://www.borla.com/products/frs_b...t__140496.html

Then use just the first, midpipe portion where the muffler is, in addition to your Perrin muffler. So the unresonated portion of your Perrin gets replaced with Borla exhaust.

I did that with my Q300 and it sounds nice and quiet (Louder than stock still). I have a JDL UEL and Motiv catted front pipe as well. Replacing anything else won't make that much difference in sound, because all the resonator volumes are very small. Borla is the only company that makes a muffler that fits in the space of a resonator under the driveshaft.
