True only in part. If you use muffs after a degoat with more backpressure than stock, no need to re-jet, etc.and removing it is a BAD idea. It is an essential part of the exhaust system. Removing it will reduce engine power, adversely affect carburetion, and make a horrible noise. A v-twin needs a crossover in the exhaust to help equalize backpressure
Wrong again. Harley only began experimenting with a crossover after 1984. Before that Sports had none and the big twins generally ran a 2 into 1 (I had 4 Harleys, so I "think" I know"). Even most of the 2011 models DO NOT have a crossover, only a few select models do. Also, around '86 or so, Harley began playing with matching pipe lengths to balance by adding a forward loop to the rear pipe.V-twins DO need a crossover, even Harley uses one.
Most likely, the cost goes into the CEO's pockets. There was a guy named Ted from Ted's Cycle Shed in Newburgh (google him, he's famous) thats been building systems since the 60's at 2/3 the cost or less of the "fancy brands". His pipes are much sought after, and although retired now, his designs live on. Im sure in his early days was much trial and error (R and D, lol), but actually, pipe in bulk is cheap, and he had his own warehouse full.Most likely more than half the cost of an aftermarket exhaust system is in research and development.
Thats a sweet ride ! Except that I dont like EVOs much. All my Harleys were '72 and older. Dont know much about AMF and after (dont care either).I also own a Harley, a '97 Road King with a carbed EVO
