ZR-1 Exhaust Cutout Project

[Tony Davila]

Still had to do a little more R&D to get the cabling right and the spring pressure to allow a solid open or closing. The pressure from the spring keeps it from rattling when in the closed mode and helps it to seal better.





Next was where to mount the cable levers without creating an eye sore and still be functional and not inconvenient.


Mounting the cable levers in the compartment behind the passenger seat was the easiest shot with the lease hassle.

The Cutouts are not so noticeable from the rear.
I also cut off the exhaust tips and moved them further out and up in order to get a neater appearance. The gap was horrible.


My impressions of my build are this, A Success!. While driving at 70MPH it is so quite I now can hear all the annoying squeeks and rattles. It still makes noise if you get on it but the sound is outside of the car not in the cab. I will only have it closed during long trips or if I don't want to hear all that LT5 excitement.

when I'm cruising with the exhaust cutouts open there is drone in the cab just like the B&B/X-pipe system and now an even louder race car sound that every one knows your coming. I mean everybody! Even people in different states.
