Good find.  Did you go with the aluminized or SS?  The price doesn't seem bad.  Several years ago Napa wanted $135 for just the stock intermediate pipe.  I'm not sure what the price is now.

Got the exhaust installed today, not happy with how it hangs down.  Flows much better though.

I used a old set of 1997 exhaust tips from another car of mine, I think the round works well.

Bye bye old exhaust.  The second pic is the water & crap from inside of old exhaust.  Will try to install the down pipe next weekend.

Center / center dynomax mufflers.  If I had to do it again id just have one fabricated.  Seems to spool a lot quicker, I'm sure the down pipe from Jerek is going to really wake it up.

Looks good. Those 97 tips look similar to what 91-93 dual outlet exhaust GP's had from the factory, just much thicker walls on them.
