Went with a west coast saw exhaust on my 2511, and took my 590 to the saw shop near me and got it muffler modded and some port work done. Did a couple test cuts out behind the house, definitely loud! Fun to run though, it really woke them both up.
Take that saw to huskihl if you want a real animal...our XS4910 will out cut our XS362 and just about keep up with the XS400. He did a XS7310 that was 2 sec faster than a XS462 he did.
