Well stock, I get a very, very slight film that's visible on grey. But this does not look right. I would be concerned, of carbon build up in the engine. My S2000 had a similar problem. It was evident when I had the head off. The tops of the pistons where covered in black carbon about 2-3mm thick.

So not everyone with test pipes have this problem on the back side?

and all this carbon is from my simple resonated test pipes????? im finding it hard to believe.

so i take it a CE light is a lil more to be concerned with than just a light. i wouldnt think id have all this from something so simple.

(side note, after taking out and cleaning off the O2 sensors, repacking the opening of the sensor hole with steel wool, and resetting the ECU i noticed LESS carbon build up on my bumper)

i think i might be switching to a high flowing cat soon......
