Question What cat back exhaust system do I have? Pics in the thread.

[Rescuerob]

So I have been going nuts trying to figure out what manufacturer/model of cat back exhaust I have, and took a few pics. For those that know everything-vette, what are these? I couldn't find a serial number or manufacturer plate. I do know that they are loud! Curious....

And yes... I need some tread....lol

Appears to be a homemade job with no mufflers at all. So yes, it would be loud.

It sure is... a little too loud. Time to change these out.

Go with Holley hooker mufflers see attached. Very reasonable - easy install for a DIY project. Put them on my 2011 GS sound great. Look good as well. They have excellent tech support go into their web page call them with any questions or concerns.

If you have a Z51 the vacuum plumbing should be all ready installed so you will only need the NPP mufflers. So then you have the load and mild. Sudden acceleration and you know you are there and then it will go stealth.

Homemade in a dimly lit shop after a few.
