l98 is a single exhaust uses 3" to 2 1/4" piping, the catback cosists of piping from the central cat back...
lt1/4 uses a dual exhaust 2 3/4" piping. The catback consists of the entire system from just below the block (where the cats are) back.
btw... a lt1 system should work nice on an l98 with LT headers...

With all of the cheap or free LT1/4 systems available here on the forum, if I had an L98 car I'd change it to one of them and get a hell of an upgrade for very little money. It would take a little fabbing at a muffler shop to hook it up, dual cats could be added easily, etc. Why spend a bunch of money for an aftermarket single system when you can have true duals this cheaply?

and that's what I'm gonna do... except I'm taking out the resonator and adding an Hpipe
