I'm a n00bie
 

Hi, I just acquired a 2006 V6 4Runner Sport, and I have a bunch of noob questions.

What tire pressures do people use for street driving? The dealer set mine at 38 and it drove horrible, is the suggested 32 best for street use?
What exhaust is good for the V6? I want something less wimpy, but not illegally loud. Are any direct bolt on, or do they require fabrication?
Do the brakes need to be bedded in?
Is there any special maintenance needed when driving in the sand, besides cleaning the filter after?

Okay, that is it for now, any help is appriciated.
