Questions & Answers


What is the "linear interconnect between cylinders"?

By Mark

Is the aggressor header the same one as in the Dominator whole system?

The linear interconnect language refers to the crossover pipe between the front and rear cylinders in the header itself. It's located on the right side, just below the transmission where the headers are closest to each other. With regard to the Dominator systems - those use different headers, albeit, there is also a crossover interconnect pipe on those as well. The chief difference, with Milwaukee Eight systems at least, is the pipe diameter on Dominator headers goes from 1-3/4" down to 1-7/8" and then up to 2" where the mufflers are attached. Aggressor pipes are 1-3/4" down to 1-7/8" where the one pipe goes under the bike's frame to the other side, and then back to the proper size as the OEM mufflers on M8 models.
