I'm with you on OE on many things, Derek.
Especially on the engine's breathing on a car that has a history of running warm...
I wouldn't want to fit a Borla system and then have Mini say I caused a catastrophic failure of some sort...
Now if Borla would offer an engine warranty as well as a rust-through warranty, well maybe.
I'll give a good look at the JCW
stage-1 kit for the AT when it becomes available.
I put an aftermarket center armrest in the car that's very nice. It opens clamshell fashion rather than sliding forward ---- no accidental openings.
