What's up all, I've never posted anything here, I just installed the Perrin short intake on my 04 STi and I feel like I lost torque especially in 5th and 6th gear. Normally the car has substantial torque when the gas is mashed in 5th and 6th now I feel like when I step on it from about 3,000 it takes forever to spool up and it sounds like the charger is losing all its pressure. I think that maybe the intake only works well if a full exhaust is also put on? Anyone else have experience with the Perrin or any like it. They're all pretty much the same intakes anyway.
