Dude,If recirc, you can hear the same HKS SSQV sound if u install a cone filter, while stock 'NO'. Its the same as loud when u VTA.

*drink* *smoke*

 

i running the hks vta also. as of now, no bogging probs. the only obvious thing is fuel is no sacraficed. i do have the recirc insert peice for it. but i noticed that in the diagram it has to be used with some sort of pipe/tube. does anyone have a pic recirculated. from just the looks of it, i say it's a tight fit for some extra tubing.
Any help would be appreciated. Thanks
T
