This low mileage truck was brought to TW looking for a simple way to increase the horse power.  Running stock at 314 h.p. at 370 ft/tq, it only seemed logical to upgrade to a cold air intake and new high performance muffler.  The crew decided on installing a S&B cold air intake kit, 3 1/2" Magna Flow muffler and 3 1/2" tail pipe with a chrome pipe tip.  To prove this was a success, dyno testing was done before and after the upgrade.   To our amazement,  the h.p. increased by 35 and over 400 ft/tq!
