Exhausts.
I bought a set of custom made RSR headers a few years back.
They are lovely and nicely made.
However, they were not designed to play nicely with my brand new and very expensive Elephant cross-over pipe. No fault of Elephant, their pipe fits perfectly. The issue is that I can't tighten the pipe fitting at the outlet when the headers are on first, and the headers won't clear the pipe fitting if the pipe is attached first. One of those very very frustrating situations where you only have yourself to blame. I managed to use a hoseclamp around the fitting and a drift to get it tight. But it'll have to be fixed properly at some point.
The other issue with RSR headers is that one gather sits lower than the other. So making them mate to a sausage silencer is a bit tricky - or at least, a job for a professional.
The other issue is that the flange on the gather is larger than 'normal'. I managed to fins a proper homemade silencer set-up with the correct flanges. So I cut them up and made my own MadMax versions, purely to avoid more complaints from the neighbours about the noise! Now that I have lived with them for a few weeks I think I might get the professionals to make me a set in the same vane, with a properly made-up support bar
