Ah ouais, l'idée est sympa, mais...

Any car that requires a very low or 'null' exhaust backflow will be SEVERELY damaged if you use this. This mostly means rotary engines, high output small blocks and most hybrids will seize up. Plus, this thing is incredibly dangerous to ventilate out, as the gasses you're trapping are LETHAL.
Also, if you over fill the bag, it can (and will) cause ANY vehicle, regardless of exhaust system, to be damaged. Whomever came up with this idea really should have rethought it, because this is beyond stupid.
