As far as I know, the HKS SSQV would be the better out of any others out there on the market. car ran perfect after this was installed, started to back fire a little bit after install but nothing serious. car was never mapped but sure this could help after installation. Car drove grand after it, and with the sound of this dump plus flat four was beautiful! All cats were left in, 2 downpipe ones and centre but wanted to decat the centre! again, car would need to be mapped for doing this.
what do you need to fit it to this car ? i got gtb too.

fully atmospheric blow off valve is a big no no on a legacy according to the some technical experts.....so i left mine standard :)
change it back if u want better performance.

Hi, how did you find the car ran after fitting this dump valve? Ive read a vent to atmos BOV is a bad idea on the BH5 GTB :(
What was your experience with the HKS SSQV? Did the car drive OK? Did you have both cats in?
