I have a 03 Cobra that makes an air brake bleed off sound when you shut down the engine and sometimes on start-up. What's that about? It's stock except for a CAI.

air brake sound on shut down
- Thread starter Jagged Edge
- Start date
I heard someone post something like this before. I think it had something to do with the bypass not working correctly. Either it was stuck open or closed. Run a search if you haven't already.

Excerpt:
"I have the boost bypass and the 2.8 pulley, theres no hissing sound at idle.
I did however have a problem with a loud hissing sound when I shut the car off. JDM found out my PCV valve wasn't in the drivers side valve cover, and everytime I shut the car off all the crank case pressure was blowing out there."

my GT sounds like it when i shut it off. it was caused by the CAI
I was wondering about that. This only started to happen after installing the CAI from Steeda which btw lowered my et by a couple of 10ths.
Thanks everybody
