Are the stock TTA & GN CATs the same?

[Dan Thompson]

I saw the underside of a TTA on the web and the CAT look the same as the stock GN gutted CAT I have for sale.

Is the TTA cat and the stock GN cat the same?

 

[1BADDAM]

Yes.

I even loan mine out to my buddy with a GN come smog day.

 

[Dan Thompson]

I have a gutted stock cat I am selling.

Hi,
Yes, to the best of knowledge, both converters are the same. If you take off the downstream adaptor, you have the same unit.
