Eric, we have sent the new animal system out to 2 seperate engine builders, that both have computerized Hewitt inertia dyno's. The only engine that these have been tested on is the sr. animal. From what they reported back to us was between 1-3 tenths of h.p. better on average throughout the entire dyno run, this was back to back against our animal pipe from last year and the new one. Is this a BIG gain, I think so others may not. We work very close with several engine builders to try and improve our products when we can. Hope this helps.
I agree with what wesracing said, you need to check with your current engine builder and get their opinion on what exhaust to run. I am sure you will get differant opinions with differant engine builders.
If anyone has anymore questions please feel free to contact me at the shop
