Hate to bring up the dead horse but I'm about to replaced my bypass valve, have we come to a conclusion as to which one really works best for our cars? Yes i don't care i want it for the noise factor.
I've always used turboXS for my wrx and my old 3000gt vr4, but i keep hearing about synapse instead of HKS so i come to all of you experienced with changed b.o.v's for assistance, i want to be able to vent to atmosphere as synapse is quiet :/
Solo high flow cat , Trifecta tune, Solo dual center exhaust, ic pipes, radiator hoses.
