After my HKS SSBOV took a crap I needed a new on. I ended up with the Tial. The piston in this thing is double the size of the Greddy and HKS. It is much quieter than the HKS. Dont get me wrong, I like the HKS and did scare the piss out of a few people walking down the street.
All in all it sounds good, looks HUGE and I dont have to worry about adjusting it.
