2001 ram 1500 5.2 4x4 dynomax cat back. So just as winter nears and I think ive addressed all my trucks issues this summer.... the list is always growing.... It begins making an awfull rattling noise.
I traced it to the catalytic converter (flow master high flow direct bolt) only about two years old. I bump it with my fist, and the rattle comes from inside.
My question is, are these flow masters known for going bad? And what are the other direct bolt up options? Magnaflow?

 

First I have heard of it. Is there any kind of warranty on it? May wanna call the manufacturer, and ask..... It should last longer than a couple years......

 

I put on the Magnaflow direct replacement and have not had any issues in about 5 years. Never heard of any others having issues with them either.

 

Bad Cat. Stay out of his way.....

 

Hahaha yess!

1 year limited waranty. I'm thinking of finding a Y pipe/straightpipe for this sucker and doing the o2 sensor trick.... any downsides to this other than riding dirty? There is no testing here.

 

Nope.

 

Where do you live in colorado ? They still test in denver but i live near colorado springs and they don't unless it's a diesel truck !
