So this has been discussed ad nauseam weather or not to switch the stock plastic recirculating valves on a stock car with the billet ones or not. (general consensus is no BTW).
Someone said it "deepened" their exhaust sound.....
I cannot understand how this would be possible. Maybe someone smarter than I can explain how it would do this. After reading about it, it seems it would have nothing to do with the "sound".
I only present this question because I'm changing plugs and coils and have been staring at these damn valves for a while now.

Most of these AM Diverter/Recirculating Valves end up seizing and the OEM's work fine. Agree, that these do not change the exhaust sound. What I have noticed is you may hear a little different sound when the valves open...more of the Turbo spool...but not a deeper exhaust sound. They are not even part of the exhaust, so don't see that as very feasible?
