I actually liked the way it sounded. I ran it this way for almost a year while I was away at school and loved it. I usually wheel at a little faster pace on old service roads and the desert with a bunch of guys with built up silverados and other pickups that make the 3.8 sound like a pansy so the sound without the muffler made me feel like a big boy :cheesy: But once I got back home I started to get back on the slower trails with steep inclines and whatnot i didnt like the loss of power in the lower rpm range and finally got over it and put on the dynomax. If I could keep the sound without the loss in power I would but that's just me :thumb:
