Interesting thread.

Going to see how this stuff plays out in the community- personally I have an issue with defeating emissions for no good reason- like a handful of possible HP, or just some misguided mindset that "emissions control is the government controlling our lives".

On the other hand, if owners are being abused financially by a poorly engineered system, which is horrendously expensive to maintain and which our US regulators fail to protect consumers (by allowing manufacturers not to warrant their work) a bypass/elimination may be fair game.

If zetatre is correct and that these systems failures are due to cascading issues (thermostat, cool running, etc) this may be an option other than bybass surgery.
