wayne_smith97 Posted December 12, 2015 Report Share Posted December 12, 2015 Yes. Some cpi's, shearers or even slp's would be a much better pipe for you. Quote Link to comment Share on other sites More sharing options...
Canada Posted December 12, 2015 Author Report Share Posted December 12, 2015 Ok, can I run them for now, till I sell for other pipes. Or will they just choke it up so bad to damage something. Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted December 12, 2015 Report Share Posted December 12, 2015 As long as there not clogged. But they will hold that thing back a lot. Quote Link to comment Share on other sites More sharing options...
