Then I would say it was fitted with LT1 mufflers from the factory Possible part shortage? I was actually at the factory in 1992,1993 and1994 To watch the ZR-1's being built and all the ones I saw come off the assembly line had dual tipped mufflers. Rectangular mufflers Outlets are listed with GM for (LT1's) only. Hope you held onto the stock exhaust it's gonna be worth money. I would love to see your VIN and check the rpo codes.

The older I get the faster I was.
