Hey folks. I have an '05 H2 SUT w/ ~150,000 miles on in. So. I started it up yesterday to go for a jaunt and was greeted by this terrible rattling noise from the back of the truck. Upon examination, I learned that I needed a new catalytic converter... does anyone know if I can use a "universal"and what type? Lotsa feedback welcomed!!! Thanks!!!!

 

Anybody???

 

I found this site that sells several cats 03-07 Hummer H2 Catalytic Converters at Andy's Auto Sport

 

Thanks Caraddict! I took it to a muffler shop today. Turned out to be the muffler and not the cat convert. Yay! Prob getting fixed tomorrow!
