Hey guys, cavalier owner here. I was told by one of my friends that one of the cobalt models has a 2.25" cat/exhaust... Is that true? (I'm mainly interested in the cat)
If not, anyone know of any stock cats that are that size?

Thanks,
Dave

 

I think the SS/SC has a 2.25 exhaust but I'm not sure. I'm also interested in the answer to this question, what are the exhaust diameters on the 2.2, SS, and SS/SC?

 

The SS/SC has a 2.5" up intill the rear axle where it goes to 2.5

Well, im assuming it's the same as the IRL

 

When fastSS06 took his exhaust off, it was 2.5" the whole way through, I looked on my SS/SC and can't see where it would drop from 2.5". But I know on the 2.4s it drops to 2.25" from the axel back, everything else is 2.5", not sure what is on the base models.

 

i have some random tech cat's 2 1/4 laying around. need to ditch em

 

so its 2.5 all the way from the header back? up until the U bend where it goes to 2.25 correct???

 

One of my friends called the dealer and they said the SS (non S/C) has a 2.25" cat. Anyone agree?

BTW Nice car SilverSS... I've got a thing for silver I think hehe.

 

no, also the flange locations drop down in size
