Tested: See how catalytic converters perform on the dyno | Articles

I’m glad this article has finally been posted.

So the Magnaflow cat is 0.5lbs lighter than the test pipe?

Impressive results and great article.

I wonder what the test would be like with something older. Say mid-80’s ish?

Makes me feel better about keeping the cat on the race car. It’d be interesting to repeat the test (circa 2008) on something turbo and something bigger.

ditto.

I just keep the cat in the e30 because without it, the M42 exhaust sounds like complete raspy garbage.

Something of that era, you’d be better off with a modern HP cat. Flow better, lighter, and even though I’m not a fan of aftermarket cats (not good info), it will still be better than the original hardware.

This was a refreshing article. I learned that my impressions were some what accurate about cat delete and high flow cat…
