I am waiting for more pipe to test.  I have the dyno Queen in the shop and I need more pipes to test.  I have tested a Dynoport, Paul turner, and a pipe that the manufacturer is unknown.  Send me your pipes and I will test them.

Would love to send ya the Aaen but the shipping cost there and back from up here to Canada would be nasty.Just curious,are all/most of the "old tech" pipes pretty close in numbers?
