Ok, so the other day i took my cat out and threw in a test pipe, and of course, few mins after driving off my CEL came on as expected. My freind told me when he was driving behind me that after i cracked VTEC there was a faint white smoke coming from my exhaust. could the CEL be throwing in to much Fuel? would i be better off runnin the Cat? plz help

 

put the cat back on your civic. /thread

 

But is that what is making me smoke?

 

well obvisouly it is,put the cat on... the cel is causing it to smoke if it didnt before. so put it back on

 

White smoke doesn't mean to much fuel is being dumped into the motor.

 

yeah its valve seals, or rings, but odd's are is the o2 readings are bad cause the cat is not there. just re install the damn cat it dont give you that much power

 

Find out what the cel is for and go from there..

 

even if it doesn't have anything to do with it, put it back on....you lose power because of lost backpressure. also makes it sound better and not like a piece of ****!! lol

Actually, you gain horsepower and lose torque..

 

thanks, il throw it back in and see if the smoke goes away, i hope its just excess fuel thats not getting burnt, would hate to find out its seals or rings going bad.. thanks guys, and btw i like the ricey sound that i get with no cat

 

im not sure if its true.. but ive always heard and assumned that of course u wuld get smoke out of ur tailpipe since the cat is removed. im not sure if u guys notice but if u go to the tracks and see majority of the cars there. tehy all have smoke out the back and dnt have cats. never heard of it being bad or good for ur car.. jus that its normal for it to smoke after removal of cats.
