I just recently purchased another d-max. I am wanting to start to get some mods and think I am gonna start with an exhaust. I am thinking 4" or 5" traight pipe turbo back. Just seeing what you guys out here think. Eventually I am gonna be getting more mod's (as the money comes in) but just figured I would start simple. I want it a little loud and deep but not too annoying when I am going down the interstate for 6 hours straight. What yall think?
