"More performance can be found, but not without the application of an optimized package, most everything I have tried has reduced performance, made a lot of noise, burned a lot of gas and killed efficiency."
Like others have said, its great to have you on board getting some solid data for our engines. I did a couple of dyno pulls with several mufflers I tried before I setteled on my Dansk unit. I was was shocked to see that I lost HP with two of them.
That was really not in my mindset, they made lots of noise and supposedly had high flow rates. I did pick up a little HP with my current exhaust system, but like Jake says, it effected my gas efficiency. Before my exhaust system mods I was getting up to 29.5 mpg on the highway with cruise control at 70 mph, with my current exhaust it is closer to 28.0 mpg. We live and we learn....
