Default Dv vs Bov?

So im gonna get my audi 1.8t chipped.
But before i do i need either a bov or a dv, But the thing is i don't wanna draw to much attention to myself but i like the sound of blow off valves?
Is there a decently quiet bov?

U can't put a bov on an Audi. Audi turbo system is internal > means it measures n recycles the air/ boost it doesn't use. Bov is external> means blows unused boost/air into the atmosphere = screws up Audi turbo system. Don't know much about turbos ( I'm a 2.8guy) but I know that much. Look at the sticky about getting an Audi n look at turbo section for more info

Oh weird, i didn't know that.
A buddy of mine was saying forge makes ones that work but i guess hes wrong.
So looks like i don't have much of a choice

No I think he's right on that one it's like .007 or sumthing don't quote me like I said idk much about turbo but the one I think he is talking about is a diverter valve not a bov

Forge makes splitters. You can set how much air you want to recirculate back.

Forge BPV for the A4 1.8t is FMCL007P or FMCL007PA(adjustable)

Forge also makes a splitter that works on the A4. Some people have even ran the Forge 004 which is a dual piston BOV.

Forge valves for the A4 1.8t

I have the Forge Splitter and run it as 100% recirc, but the vta feature is semi-subtile, and doesn't cause any air metering issues with the maf/ecu. I've seen some people run a 004 with no issues and some who do have problems with it-but I think it is also very adjustable.
