I want to be louder.

[PrestonBurns]

Already got an aftermarker muffler on. What can I do under the hood that gives my pathfinder a deep exhaust tone?

[Karmann]

High flow cats, CAI (intake noise only), and maybe a different muffler? There's not much proven tech for this.

headers, larger diameter exhaust but I wouldn't go over 2.5 and I personally wouldn't even go that large, single chamber flowmaster, delete the resonator, stage 2 cams.

Agreed!

One of the things I really like about the Q is that after 5-6 hours on the interstate I am not deaf like I am in the jeep.

On mine i have 2in into the muffler no res and the 2.75 out of muffle for tip and combined with my cai it kinda sounds like a decent sound v6 car not loud at ifle but you get on it and it grumbels

That is also what I perfer.

The only trucks like ours I have seen with a real rumble to them are not street legal. On the 3.3L the cats alone drown out a lot of the noise before it ever gets to the baffles in the muffler.

high flow cats and eleting the resonator will give you some more 'vrooom' but IMHO that can be a lot of $$ for a small gain.
