I just put on my new header and test pipe today and now my car is smoking like crazy!

Before, when vtec would engage I'd see some smoke from the exhaust. The car does burn some oil. But now, I'm getting a pretty good amount of blue smoke from the exhaust, especially on decel.

Valve seals are only like 2 years old too.

WTF???

 

with no cat there is nothing to filter your exhaust gases.... now your seeing whats been going on the whole time...

Yup. the cat is not collecting the smoke so it's all coming out from the exhaust.

 

Do peoples cars with test pipes usually smoke?

might see a little extra condensation smoke but not smoke like your seeing.
