Yesterday when driving to the Motorcader get together at Misty Mountain CG, I got my first real info since the change from the Cowl muffler to the resonator. The improvement is better than I expected. Had no real idea if it would be noticeable or just one of those theoretical ideas.
On I-64 as you head west from Charlottesville, VA. just west of US-29 you start up a little mountain we locals call the Ivy Hill, in the past, towing the Ford F150, the speed would be 66/67 mph. Last evening it went up to 71 mph.
Now I need to plan q little vacation trip to get more info, including any change in mpg numbers if any. I am now wondering if I should do the horsepower/torque upgrade.
More later as it unfolds.
That is noticeable. It must feel good to be in the outside lane going up hill.
If looking for the parts list for what I used, here tis.
Simple if your used to working with tools. Keep it simple.
My toys do not need to run the right lane for long. Since the MCI DDA major power, I prefer the left lane.

Dave,
Do you notice any noise difference?
Only with the drivers window open, it sounds about like the 6V-92 in a U300, With window shut, no difference from before.
