I have Borla headers, and am pleased with them.......when I first put them on, they vibrated really bad at 2000 RPM. I had to put a shim under the motor mount to raise the motor-on the passenger side, and this corrected the vibration. I have heard of 2 others that had this same problem. The headers didn't affect the sound of the car as much as I would have thought---the Borla cat-back did that. But the power increase is noticable. I don't have any dyno sheets, nor have I raced the car yet.....that'll happen next summer! Also, the heat shields were completely removed. Didn't affect the temp inside the car much. I also still have the stock plug wires. The headers do get hot, so I plan on upgrading the plug wires to a more heat resistant brand.
