A quick cautionary exhaust tale. A chum has a 1983 CVH engined 4/4. She took it to an exhaust specialist for a stainless system to be fabricated.

The, so-called, specialist made the system so that there was no clearance to a rear tyre. She managed around 10 miles before a blow out. IIRC, 4/4 of this era have a “kink” in the pipe as it passes the wheel to ensure sufficient clearance - its a long time since I have looked underneath one.
