Just got an 045 Stihl and have her completely tore down to swap crankcases and change crank bearings. This muffler came with and I am not impressed with it. Compared to my 045 Super, this one seems far more restrictive. I have never modified a muffler before so I don't know where to begin. If anyone has any advice or specific instructions on how to improve it I would appreciate it.
Thanks, Chris B.
