That sounded more harsh than I meant it...but the question was asked for an answer without the usual barrage or opinionated responses. I do have the system and have tried to be totally up-front and honest in my evaluation. Claims are just that...and I understand that. But I have noticed that if it doesn't give you 100 bhp and you don't have dyno sheets to back it up, then some forum members will laugh their ***** off and blast those that look for any improvement, no matter how small or in what system of the car. I enjoy learning all there is to know about this car and what is available for it...and what, if any, improvement it makes. Condescension helps nobody. Sorry for venting...my 2 cents.
