I had Magnaflow on my last T100 (same 3.4 v6 as the Tacoma). I was very disappointed in the sound as it was too soft. At idle, it was basically like my stock muffler. Because of it, I'm going with the Flowmaster 40 series on my current Tacoma.

I know you have the 4cyl, but I think the bottom line is that you'll need to ask whether you're looking for sound or actual performance gain? Having had several trucks in the past with performance mufflers, the difference in performance would be minimal if all you're doing is swapping out the muffler.

These days, I'm just doing it for the sound. And if you want sound, I would say the Flowmaster 40s.
