2011 Z06 Mufflers On a Heads & Cam LS7 – Soundcheck & Review!

Back in 2011 Chevrolet took the learnings from the C6 ZR1 program and applied them to the Z06 platform. This short video shows my 2008 heads and cam Z06 driving by, downshifting and rev matching, equipped with American Racing headers and the oem 2011 Z06 mufflers. Compared to the 2008 Z06 mufflers, immediately upon opening up the butterfly valves, the exhaust note is sharper and the tone is stronger, sharper and more aggressive. it’s more race car screamer than muscle car deep.

What makes this corvette exhaust system unique is the fact that it bangs and firecracker pops on the overrun like no other exhaust system (aftermarket included) I have installed on the Z06 so far. If you like to hear a lot of firecracker pops and bangs when you let off the gas at any rpm, this is the exhaust system for you. Downshifting to 2nd gear especially gets you machine-gun-like banging and popping.

It looks exactly the same as prior oem C6 Z06 exhaust systems from the outside, except this system has perforations on the inside of the exhaust tips. And like all other factory Z06 exhaust systems, this one comes equipped with vacuum operated butterfly valves in the exhaust tips to create true dual mode functionality. In the quiet mode, this system is almost too quiet, with absolutely zero drone in the cabin while cruising. Increase the engine speed past about 3500 rpm and the changeover to open valves is much more dramatic and audible with a much better, crisper sound. It’s a fantastic thing to experience.

According to some experts, this exhaust system not only adds a unique sound to the Z06, it also adds horsepower, as much as 5-15rwhp!  It’s a secret the Corvette engineers don’t want to admit.

Want to have more fun with the oem 2011 Z06 mufflers?  Purchase a Mild 2 Wild Exhaust Controller to open and close the butterfly valves manually whenever you want with the press of a button!
