Dual Exhaust?

What type or dual exhaust is recommended for my 03 double cab taco and what are experiences w/ installation and such?

Lookin for deep/low sound that does not penetrate interior much but noticeable hp gain.

Get magnaflow performance muffler with dual exhaust pipes, they sound great, and i can feel more power under the hood.
