Unfortunately I just tossed my OEM resonator, although the cost of shipping it to you might've been more than the part itself.

I also just remembered that the PE muffler has a provision to attach a drone reducer. It's a conical shaped rubber piece that may have been attached to your stock muffler. You just bolt it on. They're designed to reduce noises in a specific frequency range. My car didn't come with one, but you may still have yours.

If you happen to get it the noise level measured, let us know the result.
