Dual-Mode Exhaust for the Z?
Here's an interesting idea from the 'Vette people: a dual-mode exhaust. Flip a switch, and it goes from a quieter exhaust to full-performance roar. Old press release here:
Jalopnik - Yeeha!! 2008 Corvette Gets Big Boosts of Both Power and Torque - 2008 Will there be a similar system for the Z? Could be especially useful for those of us who want performance upgrades, but the cops hate the roar... |

On the Vette, you can see the two inner pipes and the flaps and actuators that control the sound. Last edited by Modshack; 06-18-2009 at 12:34 PM. |

My father has the same system on his Z06. He opted to install a "man switch" that opens or closes the system with the flip of a switch in the cabin.

At the risk of sounding ignorant...
I'm not sure you would really want e-cutouts. The amount of lowend you would lose would be fairly significant due to the lack of exhaust velocity. Also, your AF might be thrown out of whack if you have other mods. (probably not dangerously lean but possibly leaner than you would want to run the engine over the course of 100,000 miles). The flip switch system might be a better idea but i'm not sure how well the VQ would respond to straight pipes (my inclination is to say "not well"). I suppose it all depends on the stock ECU and other factors. Then again, I could be off base by a long shot. Maybe somone else has something to add/clarify/correct? |
