Butterfly valves/silencer on Fast Intentions
 

Hey first thread, anyways i was wondering if there was a system similar to the butterfly valves on z06s and gallardos that opens up exhaust past a certain rpm/or in my case with a switch that could be put on the Z. Cause sometimes u dun wanna wake up the whole town (or attract the cops). But sometimes you want a free flowing exhaust.

There is tons of room under the car for us to add electronic cutouts to make it louder. However, from a performance standpoint you would not want to restrict it now just to quiet it down!

Thanks for the reply,

I am definitely looking for an exhaust change, but i want to be able to silence the car with a switch to sound as if it were running stock even if it meant restricting performance (probably by the #hp gained from exhaust change) for that time being. Not being very mechanically learned, I just wanted to know the possibilities and the drawbacks to having such a system.

check scalcam exhaust for 370z. oohh, Hybrid Exhaust System (Dual Sound, Twin Valve) by Power Craft
