i jus recently installed my HKS HI POWER EXHAUST on my 00 celicaGT. whats strange is that my cold air is louder then my exhaust? HKS guy said it will get louder at 3000 miles of use. Is that true? sum1 told me i can drive it around for an hour and spray it with a water hose? what does that do and OR take out the resinator? should i do either or ..or will the exhaust get louder like HKS told me?
i have the HKS exhaust, and at first the Intake was louder, the exhaust doesn't get very loud, its quiet but when you get to higher RPMS it sounds amazing, it gets a little deeper the more you use it though, i love mine
