Hello, I bought repacking material and a quiet insert core for the Powercore silencer on my '08 WR250X. I watched some videos online, and am ready to swap it out, but I can't separate the midpipe from the header to safe my life. The slip-fit joint is just locked, and I can't get much leverage to try to pry them apart. I've beat on it with a hammer and flat edge bar, I've sprayed WD40 into the joint and twisted it, everything I can think of. I'm hesitant to put a lot of torque on the pipes by twisting with a extender bar, I don't want to bend or shear the pipes.
Any other ideas? I'm sick of the over-loud blaattt, and so are my neighbors I bet, especially at 6am.
thanks,
Dean
