Question Catless or not?

Since the e36 328i boasts a "true" dual exhaust, how beneficial would it be to run catless, and actually how restrictive are the cats on this car?

Well unless you know someone to somehow cheat your inspection or you plan to put it on every year, your wasting your time. Unless of coarse its a track car...

Catless or not?

The inspection is no problem...hehe...but how beneficial would it be to remove both catalytic converters?

Just get some high-flows, get most of the benifit without being illegal.

dude go for it... and mod the hell out of ur intake hehe and if you have no problems with inspection do it. my friend's prelude is like that and he's running n/a and that puppy is fast... but running a 2.8L IV6 with no cats would give u a good gain and the multiplier effect kicks in when you start doing other work on your air flow...

Do this. The cats aren't so restrictive that you'll feel much if any difference in driving the car.

In my country there are no restrictions on emissions. I have a cat and have been wondering if I should throw it away, because when my pipe broke just in front of the cat, my fuel consumption seemed to improve.
