i'm running a 2.5" open downpipe right now @ 7psi. I am just curious if the open downpipe makes the BOV a little more quiet, like alomost nonexistant? I can only hear mine now from outside the car. is it always like that? thanks for any answers

 

bump..... anyone's input is welcome

 

You running open DP or a full exhaust has no effect on how loud your bov sounds. but if you are running open DP, you are probably drowning it the sound of your bov out.

 

yeah the dp is probally so f'n loud that you cant hear it. And you have to give us more than 10 mins to respond

 

if your worried about the sound of your BOV i dont think you want to go Open DP. it's loud.

get a different BOV or use a Diverter Valve like stock turbo cars.

Or run a full exhaust setup. Kteller adn Thermal offers nice exhaust for turbos. Much quieter
