I have a 2002 E-shift (stock) I'd like to increase my 0-60 without voiding the warranty. I'm in TX & haven't seen the L-tuned IS w/c I heard is a second faster than my stock IS. The Team Lexus cars 0-60 is 6.4 seconds. Does anyone have details on what to do w/ the intake & exhaust. I was told to just replace the exhaust w/ the L-tuned exhaust & replace my filter w/ a K&N or similar ones. Any suggestions or does anyone know what brand of intake & exhaust was used on the L-tuned version because I heard that the only diff. of the stock & L-tuned IS is they modified the intake & exhaust?
