exhaust leak that you can smell through your vents more than likely are from your o2 housing area.

 

Haven't changed anything on the car. Getting ready to Just been cold so haven't wanted to.. I redid all the gaskets about 2 years back when I redid my trans so they aren't that old. Thanks again for all the suggestions. I will keep it updated with my findings. Hope I find where its coming from.

 

didn't see that custom tune by steve. Still doesn't mean its not tuned rich tho

 

i had a crack in my megan POS o2 housing and it caused the exhaust smell also for me at WOT. might be something worth looking into.

 

To check for exhaust leaks, check around the sections that bolt up and have gaskets - there will be black soot.
