Cheers Rob You've got almost zero chance of getting those dimensions , they aren't particularly easy to measure accurately without the right gear. The flanges aren't inline! Your best bet would be to get the catalysts to your guy! Quote Link to comment Share on other sites More sharing options...
Ric Posted December 29, 2006 Share Posted December 29, 2006 or copy another decat pipe Quote Link to comment Share on other sites More sharing options...
Gordon F Posted December 29, 2006 Share Posted December 29, 2006 To make them properly you will need a jig, and to make a jig you will need a good condition cat, or a decent condition decat pipe that has been made on a jig. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 29, 2006 Share Posted December 29, 2006 Or my CNC file, which you ain't having... I can't wait to see the £45 N/A first de cat pipe! Quote Link to comment Share on other sites More sharing options...

boromfccup Posted December 29, 2006 Share Posted December 29, 2006 im a fabricator welder specialising in s/s aluminium fabrications get the flanges laser cut the tubes are 320 mm long a length of s/s tubing from a steel supplier get a made up, already bought decat, set up a jig for the offsets and proceed to put a nice tig fillet run around the pipe to flange its all in the jig once youve got one right you could do these easy but the second decat is a different ball game Quote Link to comment Share on other sites More sharing options...
