Hey everyone, I have been working on the final touches of a 94 b18b swap in my 93 vx hatch. I recently acquired a new magnaflow performance cat and installed it yesterday and ran it for about 5 minutes and it felt good. I drove it for about 20 minutes today and when I got back to my driveway I noticed the exhaust was smoking white. I am curious if this is from the cat breaking in. It wasn't smokey before when only a test pipe was on, so this is just an educated guess. Can anyone tell me if this is normal? Thanks.

bump, please anyone?

 

if it was cold it could of been condensation?

 

the smoke was coming out in larger amounts in proportion to the rpm, but it was running super clean today so I suppose that the cat just had some stuff to burn out, thanks for the reply.

 

bad valves you might need a valve job, or bad piston rings

 

whoops nevermine you said white smoke lol, your headgasket could be on wrong or blown did you take it to high rpm's?

 

yea, sorry. I don't know if you read my last post but I think the cat was just burning something off because I have taken up to 7k r's pm and it burns nice and clear now. Yup Yup, thanks Honda-Tech.
