I have K&N d FIPK for non S/C Model

Flow master exhaust is series 40 with 2.5 pipes.

expect your gas mileage to drop substantially if you are the type that like the growl your Xterra will make once theses mods are done.

I would reccomend changing the routing of exhaust. Do not match factory bends if you plan on any serious offroading.

This is the second time I have done this, once with factory pipes and now after mufler ugrade.
