fitted new exhaust now blue smoke
my o4 wrx blob was fitted with a 3" miltek center section,sports cat and miltek backox but it wasnt loud enough so i have (about an hour ago) swapped it for a un-silenced center section with japspeed back box and now there is blue smoke coming from the exhaust on tickover,it was a second hand exhaust.
also my car when up on the ramps i noticed that the miltek had the sports cat AFTER the sensor which i thought was strange so we removed it,it was fitted to a resonator in the system but it was quite far back down the length of the car near enough under the back seats where as i thought the cat was around the center towards the front
it has been removed so now my car is de-catted but because the cat was after the sensor it shouldnt cause any issues right?
have i made a huge mistake fitting this exhaust or could the japspeed backbox have oil in it and now its burning it off?
before i removed the miltek system my car was perfect with no smoke in the slightest,the engines only done 33k and there is no smoke from the oil filler cap
i spoke to matt @ pole position and the car that the exhaust came from had done its bottom end
any ideas guys?

I wouldn't worry just yet mate.
I recently had to change my turbo as some oil was getting past the seal in the turbo, which was causing some blue smoke. I changed the turbo and blue smoke still came out as not all of the oil had burnt from the exhaust. It took a good couple of weeks driving.
If the exhaust you fitted was oily, then it will be that. You need to give it longer to burn off

well im still getting blue smoke,its worse after a good spirited drive
if it was the turbo would it smoke all the time? i have no smoke on boost and no smoke from start up its only on tick over that it smokes,not straight away tho-say i pull up at some traffic lights after 20 seconds or so it will start smoking so i give it a blip on the throttle and it blows it out then no smoke
when would it smoke if it was the rings/valve stem oil seals? it shouldnt be these as the block has only done 34k,uses no oil and runs like clockwork

The smoke will be worse after a good drive because the exhaust will be hotter. The fact the car it came off had bottom end problems means there is likely some oil in the exhaust. I would give it some more time before worrying about it, if your engine is not using oil then it cant be coming from your engine.

I filled mine with oil two week ago ( don't ask ) about half a litre at a guess
And for the first 20 mile it was horrendous , then gradually died down , after the first week it was still smoking like a good un after a hard run
And now I get the odd bit of smoke drifting past the window after a hard run
But it's slightly less as time goes by
