So yes you can free up some but you need to restrict you're exhaust to keep the hp you want to gain.

Firstly, Please read what I previously posted MANY times, as you seem to need the help.
If freeing up your exhaust only makes you lose power, why dont you throw 5 more mufflers on the car? Backpressure is simply resistance to flow, which is undersirable. Im not going to explain it as you would know if you read/understood that article.
No one said your classes were wrong, and I'm sure they were right for the most part, but that does not mean everything you learned in a general automotive class directly relates to high performance vehicles. Cut the sarcasm and do some research.
