Anyone Familiar with Chicago Connection????

I have dealt with him in the past. He's a nice guy. I do recommend him. I do NOT recommend TTI exhaust systems. One of the head pipes in my kit smashed up against my transmission when bolted to my 340 manifolds, and they didn't give a rip. They said I was too stupid to know which manifold I had, and it was my fault. They could never make a mistake. I do, however know what manifold I have, and know that the head pipe should not touch the transmission. They screwed up on a pretty expensive part, and wouldn't do anything about it. I make sure I tell everyone about their "wonderful" customer service.
