car Does not smoke on accel or decel or idle at operating temp. I noticed it only smokes after braking really hard or slamming the brakes. never any smoke on regular decel without brakes or in any situation. the smoke smells awful any clue to what it might be?

I had something similar, turned out to be water in the mufflers running back up to the hot cats. Take a 1/8" drill bit and make a hole in the lowest part of each muffler. You will be surprised at how much water will come out.

YES!! i believe my mufflers are full of water.... i drove the car for 2 hrs no smoke at all and did a couple wots when i had space that wont force me to heavy brake. and when i got home after the drive im able to touch the bottom of my mufflers barehand and it felt cold make sense it would stay cold if there's lots of water pooling.

I genuinely surprised there's no seep holes in the mufflers from the factory. This is something I've seen on almost all the other vehicles I've had.
