ok so i did search if there is somthing out there i didnt find it, but i was trying to get a video of my exhaust since i added the tsudo midpipe to my trd, and i noticed when i reved up to 5-6k did really mean to rev it that high but did, there was some black smoke that came out? so im still kinda of new to the car thing, but it only did it when i hit 5-6k when i reved i didnt notice it any other time, is this somthing i need to worry about? im just kinda of concerned but i didnt notice it any other time just when i hit that 5-6k range, i mean if needed i can post the video. oh here is the video any idea what it could be causing it? wondering cause after the last rev it wasnt there any more wondering maybe if i just had excess fuel in my piping maybe? http://www.youtube.com/watch?v=fx0ObJAVcmI

I think that's natural when you rev your car at cold start. I could be wrong.

it probably because the tsudo midpipe didn't have the CAT converter; therefore, the smoke come out. or you might need to get an oil change.

yea i think its normal but it wasnt a cold start though already had been warmed up for like 20 mins when i did the video, but i was told already from someone it was just excess gas that came out or it was just excess gas that was built up and blew out when i hit high rpm, but was told it was normal and not to worry to much aboutit . so im not to worried about it now.


and yea i know i do need a oil change, just hit 4k today so oil change is coming tommorro.

thanks for the answers

Bing! When you rev up you are producing exhaust and when you let off there is less flow so that gas collects. Then when you hit it the gas it gets blown out(like on an 18 wheeler).

Sometimes it can be a sign of something that needs further attention. But generally with a new vehicle it's most likely a combo of quoted post and residual deposits that can occassionally get left in the exhaust from when it was shut off. There are several factors that can cause it. But most the time it's not anything to worry about.
