hi these last few days my 98 wrx seems to have a lot of smoke coming out of the exhaust, i did a downpipe decat on it 3 weeks ago could it be running rich as oil and water levels are fine . or is it due to the decat and cold weather its a 3" exhaust from turbo back cheers j

Hmmm when the exhaust is warm after driving home then left over a period of time, the warm exhaust will get condensation inside, when its cold outside. otherwise what is the liqiud that comes out from the exhaust on start up??!!!!
