Default muffler replace

Bought an 07 base model coupe that has after market mufflers with high pitch drone. Looking for suggestions on replacing the mufflers only (if possible) with other than stock. Drone is most annoying when accelerating and is really irritating my wife. Thanks for any suggestions except replacing wife Too expensive.

NPP axle back and home made controller. Switchable loud to quiet.

I second this. I have the same set up. NPP is the best of both worlds. And cheaper than most new axle backs. NPP is factory on mine but I had to replace the mufflers because one was rattling. Got a set on Marketplace for $375 delivered. Plus you can sell what you have, because someone always wants to go louder. You might even be able to trade them.

Corsa Sport. Just a bit deeper and louder than stock when idling. No drone when cruising, but louder than stock with WOT.

You didn't post where you live. I've got several sets of stock originals. Helps if you are on the West Coast...I'm in Vegas. PM me if you have interest in buying factory originals.
