Ok, the pipe is done! Got it looking fairly good, but the testing of it will have to wait for a while. Here goes...
I´m happy with it lookswise, and I´ll hook it up to the engine later tonight to see if it sounds any different. I cannot make any tests yet tho, cause the water is kinda hard right now, I´ll have to wait for a couple o weeks to get the boat wet. By then I´ll hopefully be done with the rest too!
