Performance comparison

On the old site there was a link to the mod. Not sure if that still exists.

Basically, you cut the included muffler off and that exposes the end of the cone. The cone isn't finished, the opening is too large and doesn't meet the perforated tube. So you close that cone off to the right ID, then you fit a proper stinger. I didn't follow the Mod tek to a T, we did our own calcs and came up with some numbers and went from there. I did an inverted stinger and wanted to keep the powerband wide so I went a bit safe on all the numbers. It is very rideable, tractor-like for a 2t. 103mph is the best she has done, but I live in the city and nice ridable power band is required going stop light to stop light. It's also rather hilly in Pittsburgh, an engine that relies on the pipe too much can be problematic on a 8% grade with three stop signs.
