Black smoke
Haven't drove the camaro in 2 weeks but today its nice and sunny so drove it to work well I got on the highway pretty aggressive my brother was a car behind me and said when I got on it that some black smoke came out at first then cleared up.. He also said the exhaust smells hot.. told him its probably because the long tubes no cats and no mufflers.. but wanted to make sure mods are

Running a little rich most likely off the go, if it cleared up and didn't repeat then I wouldn't worry much.

Cool, didn't think it was anything to be worried about but wanted to make sure. I do notice when I clean my car the exhaust tips/steel holes on the GM ground effects are black, not real bad but has build up on them

Did your tuner leave you a little rich? As Vanq said, could be carbon and if you were running rich could help explain it.... I have it on mine, we decided to leave it a litle rich for as oppose to lean iot to lean on the side of caution.. Not to mention you are catless so whereass your excess would normally burn up in there its coming out the back moreso then a car with cats..

Maybe someone did a Cummins swap when it was sitting

Just rich. I sometimes get black smoke when I punch it as on the dyno.
Longtubes, no cats with a blower will do it sometimes. Just think about all the fuel being dumped in 14.7 air fuel to around 11.4. Huge difference |
