Not all Dyno charts are accurate, so don't really trust them. People in here know better than to look at Dyno charts.
Any aftermarket pipe will give you more power than the stock muffler, so as long as you have something. Answering your question on the GYTR exhaust. it's hard to install, gives you power but theres better out there, and it doesn't have a heat restricter, which will cause your exhaust to get really hot. People including myself take a look at the following: Sparks, CT, Yoshi, and HMF. All these will give you the most, but some more than others. And I don't think the Yoshi is expensive, it comes out to $395 with free shipping. Thought their pro exhaust is alittle on the expensive side. It's your budget and your choice, but I own the Yoshi, and like the way it sounds and the power I gain, so this is just my opinion.

 

Here is the bottom line.......If you want the best exhaust made, get the Sparks. I can only compare two that I have had. Ive owned a yohsi full pro comp and the sparks.. The Sparks out performs the yoshi.....bottom line. But the yoshi is still a good exhaust in my opinion.
