LS1 catback fit?

I have a Hooker catback from my LS1 that was on there before my duals, and I am just wondering if it would fit on my new '93 Z28?

Would it even be enough of a change on stock manifolds/Y pipe to even make it worth putting it on rather than selling it?

if its just the muffler back i think it will fit, but the over axle pipe needs to be bent different i think, but the stock one should work, hell just bolt the thing up and see if it works.

Does the stock catback have the 3 bolt thingy to bolt the muffler on? Kind of a triangle shape? lol. I didn't even think to look for that since my WS6 didn't have that. It was just welded on to to over axle pipe. If it has that that would be really easy

. Then I could see how it sounded really easily too.

Hey bud. The LS1 catback won't be a direct fit to the single cat. you have on the 93. You'll need an "s" pipe fabbed up at a muffler shop to get it to mate up.

As far as the muffler, I think the over-axle pipe is all one piece with the muffler if I remember correctly from when I tore mine off.

Hope that all helps.
