Yesterday morning drove over to a buddies house from a local subie forum and had my downpipe installed. Damn, it sounds nice. I love how it is so throaty when I get on the gas, and I can definitely feel a power increase in stage 2. Next mods should most-likely be some sways and endlinks.
Anyhow, While installing the downpipe, we had noticed that the hoses/piping on the TMIC is coated in what my buddy said was "unspent fuel and oil". This has me worried, but I really don't know much. It almost looked like a light brown gooey substance.
