Hi!
Does anybody have experience running stock Harley mufflers such as those from the FXD or Sportster range?
I have a set of Dyna-glide mufflers on Mikes XS headers. It looks great and fits the bike well and the sound is very nice.
My big question is the flow capacity of these mufflers. Are they in any way restrictive or should they allow a reasonably stock engine ( mild porting and K&N filters) to perform without significant restriction?
I would assume that mufflers originaly designed for a 1340 cc engine should not be that restrictive, but then assumption is the mother of all, well you know...
My problem is that I replaced the rotted out stock muflers with the Harley mufflers before i got the engine sorted and carbs working properly, so I have no true base-line to compare with...
I still have some work to do jetting the carbs properly, but it turns out the limitation lies within the harley mufflers, I will obviously never succeed.
Again, the harley mufflers really blend in well with the rest of the bike, so I'd hate to scrap them on suspiscion alone..
Any advice and experience shared is therefore must welcome!!
