Mini City 92- 998 Stage 1, Fast Road Cam, Stainless Exhaust (LCB mild steel)

Just had my exhaust brackets checked to see if I could narrow down a rattle my mini has developed Brackets brill, except that while it was on the ramps found the back box weld (w/link pipe) is split and needs welding (nothing too dramtic) but also found the manifold has been sat too far forward and made contact with the drivers side inner pot joint casing and made a groove in the downpipe hence exhaust system needs to come off to be repaired and repositioned, while its off i was wondering if its worthwhile swapping for a stainless steel lcb or stick with a mild steel one. which basically leads to my question, is there any real benefit? aside from not rotting and being generally shinnier, does cost a siginifcant amount more than its mild steel counterpart too.

In Short Pros and Cons Please

If it hasn't worn right through the pipe of the lcb, it can be filled with a bit of MIG weld, filed back and will be as good as new. There is no real need for stainless steel lcb as they simply don't go rusty and are quite strong enough. Make sure the clamp fitment at the bottom of the lcb onto the output shaft cover is fitted properly as this keeps the lcb from touching any moving parts. Often they fall off or snap or come loose, which is what allows the pipe to touch the output shaft.
With regard to the back box, that's a question of whether you want to spend out on a stainless one. I always find the standard mild steel RC40 to be an excellent box and not too expensive.
