Dual Mode Exhaust
Switch; ITEM EXS
For Z06
and 2008/9 with NPP Option. A switch to turn this function on and off when
you want is a must. If nothing else, to hear the gurgling and popping when
backing off at low speeds! The stock system closes the butterflies below ~3000 RPM
depending on year and model. With a switch you're in control!
We found a place to put the switch that is
hidden from view, easily and readily accessible while driving and requires
drilling one small hidden hole! If you want to return to stock a small
black rubber plug will go unnoticed (but anyone buying the Corvette will
want this feature-even a purest!) The PDF shows step by step construction
with photos including how we made the hidden switch holder etc. There is no
need to go to the fuse panel in the engine compartment, the fuse that
operates the Dual Mode Exhaust on both Z06 and 2008/9 NPP option is in front of the passenger foot well. No alterations of the panel or wiring required, just plug in
an “Add-a- Circuit” the way we show and crimp on the proper size wires to
an Off-0n Switch. Routing the wires is a snap since your not
going very far and none pass through the firewall etc. Just tuck them
in the console. The design maintains the 10 amp fuse and draws no
current when the car is off.
Using The Switch Is A Great Way To Increase
Gas Mileage!
No it's not the
improvement from lower exhaust restriction, doubt if that is measurable!
It's the fact that when you hear the exhaust noise and the burbling when you
decelerate at low speeds you only need to go slow! Seriously, I have
found that I do not put my foot to the floor as often when I have the
exhaust opened. No need to get to 3000 rpm to get the great sound.
In fact if you want you could use lower octane gas and if you keep your
foot out of the throttle and keep rpm's high so your not lugging the engine
it may not even have to detune itself to the 87 octane program! Yes it
does have such a program and detecting a slight knock it will revert to
reduced timing, for a least a short time!

The
scraping noise heard when driving over even a small dip out of a driveway
makes you cringe! That is the bottom of the Skid Support Assembly
hitting the ground. 
If
you want your radar detector
out of the way, the best place to install it is with a clip on the passenger
visor. The added benefit of that location is you can connect to the 12V
power available at the mirror. Very little wire is visible and
none from outside of the car. That power is only on when the car is on.
If you use the cigarette lighter and a windshield mount the power is always
on and if you leave connected for a week a dead battery might greet you!
