Generally, 3" exhaust, boost controller (boost gauge, although all you need that for is to verify your settings so you dont kill anything) and you will notice a massive difference. However when you alter the cars performance, you start other little chains.. (like fuel cut, etc.) I dont think you want to up the boost with a stock bov either.. but someone else can confirm that. And if you up the boost, I believe you will want to research modifying the waste gate. (again.. I am learning this as well, but have experienced a 10-12 psi Supra compared to stock.. and its quite noticable)
