Do they offer the Hooker Cat-Back system for the '89 L98 Dual Cat setup? If so, who does and how much is it? The listing in Jeg's is not descriptive fo rour cars so I'm not sure. Thanks.

 

I'm pretty sure they don't but I'd say check with Hooker to be sure. When I switched to the Hooker system I had to do the following:

Ditch the dual cat y-pipe for an Edelbrock y-pipe. This was easy since I already had Edelbrock headers. Then I used 3 bolt 3" header collectors to connect everything.

If you wanted to keep your dual-cat y-pipe it wouldn't be very difficult for an exhaust shop to adapt the Hooker system. Maybe a little welding but that's it.
