I have owned my F since Feb of 08 and really enjoy the car. As all other car enthuiasts you are always looking for a little more. As I always say "to much horsepower is just about enough" I am vey anal and will only purchase high end master fabricated pieces. I have been looking for an exhaust and intake upgrade for some time. After listening to all of the sound bites made available from the varoious MFRS and even talking to a few I decided on the JOE Z intake and exhaust. After ordering I could hardly wait to install the exhaust and experience it for myself. Gentlemen one word BAD ASS!!! Now my car sounds like it looks. I cannot keep from driving it in manual mode just to hear the melodious engine tone. I no longer have to use expensive fuel to ward off would be contenders the sound alone let's them know this car means business. Let's just say you will not be sneeking up on anybody anymore. This mod has absoulutely transformed this car into a truly high performance machine as if it was'nt already. For all you owners who do not yet have one this is a must get when possible. My hat is off to JOE Z, the fit and finish of this piece is amazing it had all of the LEXUS servive techs in comlete awe when being installed. There was obviously a copious amount of time that went into the r&d of this system and it shows everytime I hit the gas!!! JOE Z you are the man!!!
