Hi,I have a 2001 FXD with V/H pipes (long). It sound s so much better with the baffels out,but Im told there is a great power loss by taking the baffels out. H/D jetted the carb (thunder jet) and its seems to run the same but I havent really rode the bike all that much yet due to weather here. Can I due damage to the engine by not having enough back pressure? thanks for any help,Davey
