This pipe was on my sled when I bought it..It appears to be an slp but to be honest with you Ive never taken the heat wrap off to verify it. No dents, might clean up well (never tried). There is an 02 sensor bung welded in it with a turn in plug. $150 plus shipping. Im located in Bismarck ND. You can call me at 701-214-8755, my name is Chris. Thanks
