I have searched the archives, there is a posting on 3-20-08 on the topic of uplift muffler through Catalina.I did not see this posting on the daily topics, and don't understand why it only came up in the archives. Getting back to the important issue,I'm unscessful in ordering an uplift muffler through Catalina. I have called Chris at catalina, he said to send in the measurements of the existing uplift muffler, with the measurements of the sea cocks location which I emailed with a sketch 2 times. Still no response, I called Catalina again and got their fax # and Faxed all the info on 3-24-08 with a sketch, tell# and email # still have not heard anything.would I be better off going to a different supplyer?
