Hey everyone how's it going? I have a funny fishy smell coming from under my car. It smells around my cats. The car is a 97 M3. Anyone had this problem? What are the cheapest cats I can put on with high flow and still pass canadian emmisions?

Catco sells high flow cats for around $70.

For an E36 M3, especially OBD2 (assuming you have to get a sniff test in Toronto) I would HIGHLY reccomend buying OEM or name brand cats. $70 for a cat is just too cheap to be high quality. Spend $70 on a cat that melts down, or ruins $300 of oxygen sensors.

Do you know where I can get the mid-range price name brand high flow cats?

I would go with a DEC Catalytic Converter... I think bimmerworld sells them. It's like $500. Replace your O2 sensors at the same time to make sure you don't burn up the new cat in a few months.

Catco is a good brand. They've done me good.

Yes but the cat on a obdI car can be total crap but still be okay... it's a different story on OBDII where you have $300+ of oxygen sensors after that cat.

Thanks for the great advise.

Running the Magnaflow highflow OBDII CA compliant series on my 540i. No sniff test problems, O2 sensors are fine. You can find them for $190 apiece.

190*2 + the price of welding them up, it costs the same as the DEC OEM cats which bolt right up.
