ZL1 - NPP Vacuum Line Routing - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Hi ZL1 Owners,

I was wondering if one of you could help me a bit. I am trying to find out what parts i am still missing to install the full Vacuum system in my car. The below drawing is not very informative and i was hoping someone could take a pic of that line going to the back of the plenum on their car.

Any help would be very much appreciated. thanks in advanced for your help.

Would also be amazing if someone could show me where the metal vacuum line runs under the car. does it go behind the heat shield?

I am pretty sure that connects in the front of the engine on the LSA...

I wouldn't worry about running the vacuum line. Most people who have the npp exhaust pull the fuse so that the flaps stay open all the time.

On the ZL1 the NPP vacuum line goes to the front of the SC on top of the snout.

Problem is i have a convertible that originally had the resonators in the middle. When the flaps are open it is too loud for my taste.

Good reason.
Hope the install works well.

Here's a link to when I added NPP to my V6 Camaro.

The line labeled #5 goes down behind the driver's side head along side the transmission. It runs along the transmission tunnel down the driver's side and behind the heat shield in the tunnel. It then goes over the differential and switches over to the passenger side of the car and ends in the back corner of the passenger side under the trunk near where the rear bumper cover attaches to the rear quarter panel. There is also a line that goes in the back from the passenger side to the drivers side for the other muffler. That line attaches to the rear of the differential. Hope this helps a little.
