had my 2003 wrx for about 4 months now and yesterday i put on a catless up pipe that i got from someone in trade. the pipe was already heat wrapped and i sprayed it with the high temp silicone in an attempt to keep some moisture away from it.. fallowed the instructions and heated the pipe after i painted it to cook the paint on.. then it sat for a couple weeks till i got a day off to install..

Now its on and when the car is heated up it blows smoke like its the end of the world. i can see the clouds behind me as i drive and when i stop its as if the engine is on fire its coming out ever were.. i have done heat wrap on other cars and this seems way worse then usuall.. any ideas on whats going on here
