I have a damaged one in the shed which I am happy to destroy to answer your question when I get some spare time. Give me a couple of weeks and I'll get back to ya
I've got some ideas, but man, it would be a major fabrication process. I've got some Harley CVO 4" can pipes. I have had a pair apart before and the pipes inside could be used to replace the stock piping. But by the time you got through, I'm not sure it would be worth it?
What about the TOR pipes. Has anyone ever cut one of them open? The pictures the other member showed were stock pipes right?
I would say TOR's are 4-5 times louder than stock. You can hear sounds like injectors ticking, water pump swishing and timing chain rattle with stock exhaust ... With TOR's you need to wear ear plugs.
