I have for sale a set of SLP twin pipes with silencer for 2005-2006 Arctic Cat M7. SLP claims a 13hp increase. Pipes and can are almost new. They have been on the sled for around 100 miles. Includes Exhaust flanges and springs. $300 plus shipping. I have printed off installation instructions from the SLP website including fuel mapping, jetting and clutching info. Call or email
