Not sure who has experience with this platform, but I finally got the beast and I'm already itching to mod it. It's got a very healthy 4.3 vortec v6. 235/75/15 tires, everything else stock. Rated at 200hp/248ft/lbs. Oh, it's full time awd 35% front 65% rear. Looking for advice on exhaust sizing, mufflers, tuning, suspension.
