IMHO removing the baffles totally from a muffler just makes it louder, might lose low end torque..and you'll probably have some other performance issues if it's a non UCE model. Supposedly the ECU on those remap the injectors as the engine runs..don't know for sure.
With a short muffler you are reducing the restrictive area of the original muffler w/o lowering the torque greatly. Also saving weight along the way. And should notice a gain in HP. I can explain it better for Japanese bikes with fuel injection that I've changed the air cleaner/exhaust on to open them up..but also had to remap the fuel injection system to compensate for lean burning conditions.
But I can sasy if I run the mufflers on my 2000 Drifter w/o the baffles I lose performance (torque) and increase noise. So there's my 2 rupees' worth of knowledge onthe subject.
But Tandoori chicken sounds excellent..get the curry ready.
Will.
