I just put on a pacesetter header, Magnaflow Cat, 24" glasspack, 2 1/4 piping, and 2 offbrand mufflers. Started the car up and the ppl behind the car said it smoked. i didn't look for myself yet because i had to leave class at the time i started the car and i had to leave it there at school but Why would the car do this after a new exhaust? never did it before.
Could just be something in the exhaust thats burning out. I've seen a couple people after they put on exhaust get some smoke. also could be that fresh cat to getting heated up and burning a lil bit.

Give it a week, its probably just the coating on the inside of some of the pipes. I wouldn't be worried about it, my borla exhaust did it too.
mine did that for about a month or so, just the carbon burning out from the cat, and probably in my case, the head from the Header (more flow etc), it went away though.
That should go away after a few heat cycles, when they make the exahust tubing there's a tiny bit of oil on the tubes from the machines that draw it.

give it a week or 2. mine did that

same, new exhaust smoked good when I first started it up.. You've increased your flow a significant amount all that crap in there is now being blown out as well.

Actually, no. Increasing exhaust size or installing headers may improve scavenging and reduce resistance to exhaust flow, but at any given RPM in a naturally aspirated application, total flow is pretty much a function of engine volumetric capacity. The engine is an air pump. It pulls in a given amount of air to fill its cylinders and pumps that same amount out, regardless of whether the exhaust is stock or custom. What the custom system hopefully does is reduce the overall resistance to flow and the accompanying parasitic effects on delivered horsepower. In point of fact, a larger system will actually
reduce exhaust flow rates (the air speed) rather than increase them.
