How much do our 4 catalytic converters weight total?
 

Anyone know? Thanks!

Didn't find much, but maybe this link will help you. Some exhaust stuff in there.

I just tried to weight them for you:

Attachment 1060800

But my stupid scale won't display the weight because its too light, I can push down on it and the lowest reading I can get looks like 11 or so pounds.

So I would say its probably under that, after you account for replacement pipe weight, probably not enough to worry about weight savings.

Can you weigh yourself and then hold them for a weight difference?

That's a very good idea haha, not sure why my brain can't think of stuff like that.

28.7 lbs

I have a little extra piping where I cut the secondary cats, I also didn't way the stamped steel crossmember holding piece either but I don't think that would even make a .1 lb difference.

Also for reference, 25.4 lbs for both stock headers and heat shields and stock gaskets.

That's good info! Thank you :happy0180:

Dude you went above and beyond! Thank you so much for that. You're a legend!

No problem, it helped that I have them conveniently "stored" in my living room haha

I am close to regretting taking off the stock system and cats and replacing it with kooks, all aftermarket exhausts just sound so bad to me since they let it all those exhaust pulse noises that just makes the car sound like an old broken and rusted work van or truck with an exhaust leak haha.
