im running the slp pipe with the thing can and a stage 3 kit. runs good but al made me a different thing cooker can to go with my stage 3 kit. got a buddy with thing can on the a stock set up and it runs great!!!
iv got the stage 3 on my 2014 pro and i just took it for a quick rip up and down the field since we're lacking snow but i've also found mine seems to have a bad bog at that 6000 rpm
