Long story short, my father bought an 08 883C used and it already had a stage 1 upgrade with Rush slip ons. We can't tell if there's a baffle or not (there seems to be in my opinion as I see what look to be "spring like" items in a vortex shape inside the mufflers.) if it DOESN'T have baffles, great, we'll get the 1.5s and put them back onto his custom and it should reduce the sound immenesley..? If it DOES then we need to find a quieter (considerably quieter) muffler. You see, my father believes the pipes to be too loud. We swapped my stock 883 pipes onto his already Stage 1'd 883C. Now the HD techs have told us that while it's not "that" bad for MY 883 to have the rush's it's very bad for my dad to be riding the last few days with the stock ones. :small3d023: The HD techs said they couldn't reverse the ECU programming back to stock, (which makes sense since it still has the air cleaner) but at this point we need to do SOMETHING so he can ride it again. Any takers/recommendations?
