No no no no, I never said it was more powerful or anything like that. I really doubt I got any more HP. I did notice a change in the sound and that is what I really like, and (I am probably wrong here) I think the car has less trouble sucking in the air therefore at full throttle it gets to the redline faster or it makes me think so.
But hey, I like it a lot just for the sound, I didnt expect any dramatic changes.
If you think it is a piece of crap, fine, mine is a goood cheap addition.
jmtc guys.
