    I installed this product in a Ferrari 308 QV and it’s by far one of the best decisions I made. Performance is increased considerably, I think I gained at least 10HP, motor runs cool and no more “speed down” alerts in dashboard due to CAT over heating. Even the bumper and rear of car is with a normal heat temp and not melting like it was with the CAT installed. Sound improved and now it is more deep and attractive. 5 star to this Fabspeed product.
