White smoke only in low RPM's when accelerating

i noticed today when i was on the highway during rush our traffic (more like stop and go traffic) that between 1500 and 2500 rpms i had a small cloud of white smoke exit my exhaust... It wasnt like a constant smoke, only like a cloud that exitted when i began accelerating then it stopped. higher rpms was perfectly fine no smoke what so ever..

Recently installed an Invidia 70mm test pipe (i know it smells like *** and harmful). Dont know if this can cause it.

If anyone knows why this could possibly be happening please lemme know!thanks again for any help.

BBD

Sounds more like blue smoke vs. white smoke...white smoke would be steam and a possible head gasket issue, cracked head or block. Blue smoke (which can look white...I guess) is oil burning and would think from what you mentioned that it would be valve seals...check and see if you get that smoke when you start it up in the morning for the first time.

Well, is it happening all the time now?
If not I will not worry about it until you see it again.....and again.

Unless of course if it is white and he has head gasket issues...need to fix immediately...if not sooner.

Easy way to check for head gasket is leak down test...that will make it show its ugly head most of the time.

.....at one time I replaced my sparkplug, the car smoking blue - it looks white too. It took a few blocks before the smoke settled.
I found out, the oil leaked from the sparkplug boot and dripped to the cylinders (could be a lot in each cyl).

Just keep on eye on the smoke...hopefully it's nothing.

Might just be any oil or residue in the test pipe burning off kind of like installing a new cat.

I have the same issue and see it a lot in earlier 00-01 S2000s. White smoke is also the color of un-burned gas. Seeing as these cars run rich, and it started happening after you removed the cat, I would be willing to bet that's what it is.

Black smoke is improper/incomplete combustion. White smoke is gas that has not been burned. Although both caused by running rich, they are two different things.

You can pull your spark plugs and see if one of them looks different than the rest on the combustion side. If you have a coolant leak it will literally steam clean the plug. Or you might just need a new set of plugs. I've found the NGK iridiums hold up much better than the platinum.
