MAC ProChamber H-Pipe Review
We had some issues installing this pipe, but the pipe itself wasn't the problem. The nuts fastening the passenger-side of the stock h-pipe to the headers were *extremely* tight. My cousin and I succeeded in mangling these nuts enough to warrant use of a torch. On our 2nd installation attempt, we had the car up on a rack and my father and his friend teamed up with a 4-foot extension, a 6-pt socket, a hammer (for making sure that the socket is on the nut), and an impact wrench. They were victorious over both of these nuts within 2 minutes!
After wrestling all of the o2 sensors free and removing the stock h-pipe, the next thing we did was remove the factory ball-socket studs which fasten the driver-side of the h-pipe to the headers (failure to do this will result in leaks because of the spacers on the studs). We accomplished this with a small monkey-wrench.
Once we got the MAC h-pipe lined up for installation, we realized that MAC had a surprise for us:
We managed to dig up a bolt and nut that we could use in place of MAC's surprise stud:
We finished the installation and started her up. Awesome sound, no leaks. I got in and took her for a spin. It felt good and sounded good, I was pleased:

I went about 200 miles before the infamous check engine light came on. I ordered some BBK MIL Eliminators. 30 minutes after installing them, I reconnected the battery, started her up, and the damn check engine light was still on. I consulted the forums and read about someone that disconnected their battery for an entire night, then reconnected it and the check engline light went out for good. I gave it a shot, but instead left the battery disconnected for a handful of hours, then I tested the car and the light was gone! I went about 300 miles before it came back. I haven't tried them yet, but I hear that people haven't had these problems with Steeda's MIL Eliminators.
Here's one last picture of MAC's h-pipe:
I highly recommend this pipe.
