Absolutely no drone. Honestly when the engine isn't under a lot of load (i.e. accelerating) you really can't tell anything is different.

It is an option with AA not sure which tuners actually offer this, though.

Ignorance is bliss. Catalytic converters clean up noxious gases from exhaust fumes that have been known to cause cancer. So even a truck driver with catalytic converters has every right to get on your case, even if they do 1mpg.

What you have done sounds really nice, but there is no excuse that should make you feel better.

Not that it will matter to you, but really, removing cats is bad for the environment

I hope only a handful of people are removing their catalysts.

There are all level of anything; the M3 is my one guilty pleasure in an otherwise pretyy sustainable life. IMO removing the cats is not a responsible thing to do. Do race cats if you want more power and sound.

i dont think ANY of us can complain about other people 'ruining' our environment by getting rid of our cats....

Everyone here is screwing up our environment in one way or another.......

That is the LEAST of our worries-

I'm not some radical greeny, but I disagree with the assertion that small choices we make son't add up to a very big difference. The stock M3 emits over 1 lb. of CO2 per mile. That's to say nothing about NO2 and HCs. Catalaysts are effective at reducing all three pollutants by up to 90%.

Car and Driver called the catalytic converter one of the century’s 10 best automotive breakthroughs and the Society of Automotive Engineers selected the catalytic converter as one of the automobile industry's 10 greatest achievements over the past 100 years.

Car enthusiasts ought to be aware that we are under increasing regulations and scrutiny. Deliberately bypassing effective devices that have limited impact on performance is counterporductive to our goals.

To say you shouldn't be concerned because we are all screwing things up is a pretty narrow view, to say the least.

I'll get off my soap box, and that's all I have to say.

Edit: The reason I'm so sensitive to this is, as an architect, we are trained to reduce the impact of building on the environment, which translates to all kinds of impacts. My professional organization has the goal of making buildings self-sustaining with no impact or use of off-site resources by 2030, which is technically achievable for many buildings.

+1

There is no comparison between choosing to drive a car that gets 15mph over a car that gets 30 mph and choosing to drive a car without cats vs a car with cats. Simply no comparison. Cats do a tremendous job in scrubbing pollutants. You don't simply double your impact by removing them. It's much much worse.

lol at this thread.

There are people here in the Uk driving Sierra Cosworths etc with very low MPG and absolutely no cat. They spew black smoke, grey smoke and blue smoke out the back all the time. A very clean running M3 without a cat is still a million times better than the average Pre-cat car.

Doesn't make it good to compare it to the worst. Ideally, high performance should cover all aspects of the vehicle, including emissions, IMO.

Each of our actions has some impact on issues facing us, whether it seems like it or not.

If you want to be environmentally responsible,get you a Prius or something more fuel efficient like 25 MPG.there'll be less production and transportation of gas to be used in your thirsty M3.

Or maybe you think drilling,oil tankers,refineries,diesel trucks used to carry gas etc. don't pollute.

It's like having an H2 hummer as a daily driver as long as you have a catalytic converter you've done your part.

silver mr point's is that it's really hypocritical to lecture someone on catalytic converter removal while you're out there wasting gas in your V8 sports car around town. A 335i would be a good alternative...hahaha
