I am having a hard time finding anyone who makes a catback for my car. I have an 89 IROC 350 single cat VIN 8. The only company that makes an exhaust for a VIN 8 car that I could find was Flowmaster. Is there anyone else that makes Catbacks for my car?

Also does anyone know what size pipe I have going from my cat to my muffler?

hooker doesn't make a catback for a 350 or atleast Jegs and summit only sell on for the 305.

yes they do, you need to find the correct part numbers and then do a search on summit and jegs. slp makes a nice 1, flowmaster has a nice 3in. inlet, dual 3in outlet i have been looking at. hooker sounds pretty nice and is sure cheap at 260 and MAC flowtech which i am just starting to really look into seems decent.
flowmaster with dual 2.5 in. outlets:

hok-16823 is the number for the hooker catback at summit it will only give you the price though checkout hookers site for system details. its 3in all the way to the muffler which is the main thing.

This is from the sheet that came with mine:
Part No. 16823 cat back; 1986 - 92 Camaro; 305/350 engine codes G, F and 8.

I was going faster than I'd ever gone before but then I fell off.

its only hollow piping, you're not buildig a house. It hard to find catbacks for dual cat cars because there is a Y pipe behind the cats. Cut the cat flange from a normal catback, get the right size reducer and hook them up with clamps. Hooker 3" catback can be had for $200 for older 3rdgens. It has the 4 bolt cat flange. Just cut that off and have get a 3" to 2.75" adapter or have a muffler shop fix it for $25
