Stock axle back 2.75" or 3"?
Just curious what the OEM tubing size is for the rear section of our exhaust is...
A lot of guys are saying aftermarket SS exhaust setups will fit our ZL1's...I am debating getting a Corsa 2.75" axle back (if it fits) or complete Stainless Works kit. Thanks! Scott

Pretty sure it's 2.5 in the normal spots. It reduces down going into the muffler and from a cutaway I'd seen, it looks like it reduces a little more inside the muffler. Most say the flattened part under the axles doesn't matter. Which it doesn't if you keep the stock muffler, but it looks like there should be gains replacing that piping too, if the muffler gets replaced.
