Yep, I had...but when my moms husband took it to his job to sandblast it, he overdid it...and made a whole buncha holes in it. So, he welded the holes up, and the pipe looked like someone made a sandblasted metal terd.... SO I decided to make a new one, as well as a better one, since I was not sure of the previous calculations I made. This one is far better fit for the engine I have, since I made some mods to the engine since I made the first pipe.All this was done beacuse/while waiting for my other stuff to arrive. Had to get me a stuffingtube and some other stuff to continue with the build. Next step is to glass it in, and then I can make the radiobox. After that, I´ll glass the outside, and make the thing look good, and I´m in business...=)
