Hmmm, I haven't got a clue where to go wheelin'. I haven't gone yet. My Blazer I have is just a stock one, but I finally got a 90 Jimmy that is BIG, but its just a 5000lb paper weight right now. As for a 4x4 shop. I go to HOOZE 4x4, near where I live. I had my dual exhaust done there and I think they did a good job, LOUD. I've had other things done there too, u-joints and stuff, and I feel they do a good job and don't try to screw you. They have a bunch of lifted K5's there, so I love that place. They have some products in there to look at: shocks, tires, lift kits, ect. Its a brand new building that they built not too long ago. I drive by everyday and see all the awesome trucks they have there. If I ever get around to it, I will take some pictures of my 5000lb paper weight.
