I recently did a muffler delete and flap delete, but kept the resonator/rear cat in place. The sound is a lot louder than stock, but a little more of a "popping" tone than I'd like, if that makes sense. So I'm planning on adding a muffler back in place, I'm thinking flowmaster, as I'm just looking for a low rumble versus the higher pitched tone. My question is... is there a muffler that would make the tone of the exhaust sound nice without removing the rear resonator/cat? Or would it be best to just remove it regardless? I'm not looking for a crazy loud truck, just a smooth, low rumble.
