I have the Jardine cat-back setup on my 4Runner. It's a decent muffler with a little bit of a burble to it but nothing loud or obnoxious. And it stays pretty quiet when you accelerate but it does have a performance tone to it. I think any of the turbo style mufflers should work fine. I would recommend going with a full 2-1/4" system though and not just the muffler.
