First and foremost I know bugger all about exhausts. I've brought a 1988 Suzuki GSX400E (Twin cyl). The exhausts are buggered, rust has caused big holes in them.. What's the best way to go about fixing them? Chop off the head pipes and then weld on a new cone? (Cone is what you call it.. right? Lol). Guessing that repairing them is pretty much a waste of time.. They're really rusted out. Trying to find a set of them is proving very hard.
