What kind of exhaust does the SS without the dual dual come with? Is the same stock catback as the z28 with different tips or what.

The standard SS exhaust is the same as the Z28 except, the muffler is approx 5 inches shorter and has 2.5 inch outlets instead of 2 inch like the Z28. The y-pipes are the same. The intermediate pipes are the same at 2.75 inches and they decrease down to 2.5 inches going into the muffler. The tail pipes are on SS are 2.75 inches but decrease down to 2.5 inches going into the muffler and for the Z28 the tailpipes are 2.25 inches and decrease down to 2 inches going into the muffler. I dont know why GM decreased the pipe diameter going into the muffler both inlet and outlet, but they did.
Measurements are taken from the stock cat-backs off of my 02 SS and 00 Z28.
