what you think?

i think every exhaust website should have sound clips and pics of cars with the exhaust on it....helps alot with knowing what the car will sound and look like roughly....I donno how much of an increase you would get with that....they usually just hype it up most of the time....but could be wrong too.....but someones gotta buy it and find out right???

Sounds like another exhaust gimmick to me.
