  4. Hi Guys, I am driving a IS200 and recently I had my 2 x pre-cat removed. My Main-Cat is stock. But whenever I reach High RPM around 4000-5000 rpm I could hear a high pitch sound coming from the main-cat. Any idea on how I can fix it? BTW is it normal that stock exhaust will sound louder with the pre-cat removed? Your help is greatly appreicated Thanks N C
  5. Hi I heard that with lightweight rim and tires we can improve the pickup of our cars (IS200). 1. Is it true and by how much? 2. What is the weight of our stock 17” rim with Dunlop SP9000? 2. I intend to upgrade to a 6.2kg rims with light weight performance tires. I am not sure what type of lightweight performance tires there are out there. Any recommendation? Will these configuaration provide better performance? 3. Is Continental SportCompact 2 and Yokohama AVS dB a lightweight performance tires? 4. Which one is quieter? Are they more silence than Dunlop SP9000? Thanks N C
