considered radical mods that would have an adverse effect on the functioning of
the car. Within reason, you have every right to modify your intake and exhaust,
as long as the emissions system is not tampered with...and thats between the

What I've done leaves the warranty completely in tact, or I wouldn't have done it.
All I have done is to increase the breathing efficiency of the motor, thus the small
increase in horsepower as a result.
