I know I know...

You guys are probably saying, "didnt he search before posting"

and I DID!!!! Didnt find anything helpful.

I have a B6 3.0 A4 but recently bought myself a B6 1.8t and gave the 3.0 to my g/f.... anyways... what is a good diverter valve that I can buy online that will give me somewhat of a BOV type of sound. All input would be awesome! Thanks

 

keep the bypass valve... BOV isn't a performance piece... just makes sound. Audi stock setup uses excess boostby routing it back to the compressor side not only to prevent compressor stall but keep the wheel spinning between shifts helping you to reach boost faster. BOVuses excess boost to make a sound.
