Typically Stillen makes good go-to products for the Altima, but I'm unsure about anything for the 5th gen. It's going to be difficult to get the sound to be too deep on a 2.5, but a deeper-than-stock tone can be found.
You'll have better luck finding a deeper tone with a full catback as well. Larger piping with consistent diameter makes for a deeper tone as well, and the Altimas tend to have piping compressed and expanded in random areas throughout the system for ground clearance, emissions, and NVH reasons.
