It's basic principle on airflow...others may agree on this...that obstracted airflow does not gain any HP! If Borla is really good then why are our Crossfire autocrossers don't jump into it? Plus, does Borla have a performance dyno on how it can improve our system? If there's one, can you post a pic of it? It can be a good reference source for everybody and might even convince me to get one.

And if you're happy with your borla...enjoy it if you think it's worth the price!
