I want a louder, better sounded blow off valve. Mine is quiet and just a slight pshh sound. I am looking to get one like some skylines run, a higher pitched almost whistle. Does anyone know what I'm talking about and can you reccomend me a blow off valve? I'm thinking the sound I want would be from an HKS blowoff valve as ive seen many skylines with them. Any reccomendations?

 

Get a HKS blow off valve if you want that sound.

 

RFL is pretty loud, i had the ssq on my boosted d and it wasnt that loud

 

i personally like the TIAL bov. its rated very good and been tested not to leak to 80 psi.

 

I found that I really like the sound of the Greddy type S. Does anyone have an opinion on whats better, an HKS or Greddy Type-S? Which would be louder?

 

a blow offvalve is going to do the same thing no matter of the company. i have a rfl and its loud
