Homeboy, I'm running stock exhaust manifold. Headers may come later. I have a 2000 so the post cats do not have O2 bungs. With the TS pipes added the car does breathe much better. Throttle response is really nice. So far there have been no codes.

The workmanship looks nice!
However, I would be concerned about galvanic corrosion. I'm not sure what Pedro's pipes are made of, but it's likely to be on the anodic side of copper. Steam on those early morning start ups will make a nice if not slightly acidic electrolyte...
