High Flow Convertors
I've wanted true duals on my truck for the more than 10 years I have owned it. It needs new cats anyway. I wish we didn't have sniffer test here. So I am now finally going to do it. I'm going to run a pair of Dynomax Ultraflo mufflers. I think this would be a great setup for the future 351W.
Here is my question. I'm wondering what everyone has been using for high flow cats. I have looked at the Magnaflow ones. A couple of shops have told me that Cherry Bomb cats are good. I would like some small/short 2.5 inch ones. Which ones are good and which are not so great?
Also, Do I need to plumb the AIR pump to connect into the pipes before both cats or do the new high flow cats not need it?

I have a Magnaflow cat on my truck now that is falling apart.. the honeycomb is loose and rattling around inside.. and it's only a year old give or take so I'm not that impressed with it.

Which model did you get Paul? The spun series model I purchased has a metallic substrate instead of ceramic. 2 years on it with no problems so far.

I have two magnaflow cats actually.. the newer one is a 94000 series oval universal and that is the one that is coming apart, the older one is a 54000 series round and it's still solid.

Ouch.... That is not a very good story at all. Perhaps a bad batch or someone "drop shipped" it before you received the newer model.
