GN cat

[rowilson]

How hard is it to find a good OEM cat for an 87 GN and what are they worth?

I know its kind of pricy, but Napa auto parts carries an OEM direct bolt in cat for the 87 GN. All you have to do is unbolt your old one and this goes right in place of it with no mods. It runs $170. Heres the link. NAPA® Online
Just call up your local store and with any luck if there is a distribution warehouse nearby it should only take a day or two for them to get it to their store.

Someone just put one for sale in the parts forum, not sure how much they want.

Wow new in the box $700.

Wonder how much a nice used one is worth
