MoTox8410 Posted March 20, 2005 Report Share Posted March 20, 2005 as the subject said what exactly does the resonator do and what does the inside look ???? just hollow???? Quote Link to comment Share on other sites More sharing options...
GOT2B GM Posted March 20, 2005 Report Share Posted March 20, 2005 I think it is a perforated pipe inside surrounded by fiberglass matting. Its purpose is to tune the exhaust tone and take away the raspiness (sp). Quote Link to comment Share on other sites More sharing options...

mfewtrail Posted March 21, 2005 Report Share Posted March 21, 2005 It cancels out certain sounds..but basically does what was posted above. I believe most(all?) use the reflective principle to bounce sound waves against one another in order to cancel out certain sounds/frequencies. Do a google search on "Helmholtz resonators" and you'll find more information on them. Quote Link to comment Share on other sites More sharing options...
MoTox8410 Posted March 21, 2005 Author Report Share Posted March 21, 2005 so do they create any backpressure?? Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted March 21, 2005 Report Share Posted March 21, 2005 Very little if any at all. Why would you be so worried about backpressure? Quote Link to comment Share on other sites More sharing options...
MoTox8410 Posted March 21, 2005 Author Report Share Posted March 21, 2005 just curious..... Quote Link to comment Share on other sites More sharing options...
Lee Posted March 21, 2005 Report Share Posted March 21, 2005 If you find a flow tech "purple hornies" glasspack and look inside, you will find the same scallop cuts as in quality motorcycle exhausts. At least the older ones. I haven't looked down many cycle pipes in the last 10 years. It is a heavier steel and seems to be better than most packs. I've had mine on for nearly three years. I did paint it silver though. Quote Link to comment Share on other sites More sharing options...
THe_DeTAiL3R Posted March 21, 2005 Report Share Posted March 21, 2005 I wonder if my 3100 would sound more like a 2.8 if the resonator was removed... I miss that sound. Quote Link to comment Share on other sites More sharing options...
