ZR1 exhaust on a Z06
So I've come into possession of a lovely ZR1 muffler set with 1000 miles for free and was wondering if it was worth while to swap it on my Z06. The part numbers are different between the two and the exhaust note seems much different.....I could have sworn someone compared the ZR1 exhaust to the Z06 exhaust modded. Thoughts ??

That does sound good !!!
My original intent was to just do a Corsa exhaust and be done with it.....but now that I have the ZR1 pipes a nice set of Kooks headers and x-pipe cleared the budget. So I'm thinking it will sound down right vicious.

I also have a Mild 2 Wild switch also, called the Dash Commander I think, that lets you open or close the butterflies with the Reset button on the dash. The only times I close it is when I leave the house because it will setoff the car alarm on the Tahoe in the driveway, and when there is a cop behind me.

Here is a litle more clear video of the car on the strip.
You will enjoy those mufflers, guaranteed.
They do neck down a little as well.

Has anyone confirmed yet if the ZR1 mufflers are the same as the new mufflers on the 2011 Z06?

Very nice RR !!
Guess that settles it.....headers, x-pipe, and ZR1 cans. Out of curiosity....does moving the o2 sensors down stream in the long tubes affect the emissions to much ? Past vehicles I've had get a bit squirrely about moving the sensors down stream and not getting hot enough to burn off contaminants.

Long tube headers will cause a check engine light.
It may help you to understand the purpose of the four different O2 sensors. The front O2 sensors are monitoring air/fuel ratio for each bank and reporting to the ECU which is then adjusting fuel inputs.
The rear O2 sensors are also monitoring air/fuel ratio, but are behind the Cats. Therefore the rear O2 output should be flat (the Cats should burn all the O2 and fuel remnants). Occasionally, the ECU runs a Cat check right after engine start up. It is checking that the Cat output is still 0. The Cats are normally installed right up next to the cast iron exhaust manifolds. This is so they heat up to operating temp immediately and "light off".
When we add long tube headers, we relocate the Cats further down the pipe and now they take longer to light off. Thus, even when you use Cats in a long tube header car, you will occasionally get a check engine light because it did not pass the initial Cat start up check.
Tuners will turn off this report by having the ECM ignore the rear O2 sensor inputs.
