diverter valve
 

Hey guys. I just installed a Forge 007 DV on my 99.5 B5 A4. I was wondering if there is a reason why i dont hear any difference in the sound of it. I took it off my friends 50th anniversary GTI and it was real loud on his but makes no difference on mine...any thoughts?

He probably had an aftermarket intake/cone filter. The stock airbox muffles the turbo/DV noise.

I have a K&N cold air intake on the way just needs install..will that make it louder?

RE: diverter valve
 

yup

also if your friend is chipped and your not it would be louder becasue of the more boost released

yea he has a GIAC but i have yet to get one. We had to link a larger vaccum line to the small one on my car for it to fit. will that cause any problems, like should i buy a bigger line? or will it be fine the way it is

yah man if you have stock everything but the DV you wont hear anything, aftermarket intake is big diference from stock(in sound)

RE: diverter valve
 

Should be fine
