It's an 02 Trailblazer 4x4. I love this thing, I wanted an avalanche but the wife pitched a fit so we settled on this. It has the 4.2 I6. I've added a K&N 77 series Air Intake and a Custom MagnaFlow Dual Exhaust. It sounds great especially under full throttle. I really want to lift it but the only lift available is 1.5" coil spacers, there is one guy working on a lift of about 4-6" that will fit 33's but the guys down a chevy was high when they designed this thing. The CV Shaft goes through the oil pan . This puts a damper on lift kits Anyway.. Give me some feedback about it.. BTW.. before I get crap about the mufflers in the back you would understand if you rode in one without them. I took two mufflers off and put 3 mufflers on. The resonance on these things are horrible, it's not as bad with the resonators in the back.
