Tail Pipe Finishers
Tail pipe finishers in bright stainless steel were offered, depending on model, as standard fitment (usually certain limited editions) or optional equipment.
It's just too confusing to try to list the correct tail pipe finishers for each exhaust system, because down through the years the exhaust pipe suppliers
to Unipart and Rover have manufactured what should be the same system with different diameter tail pipes! Thus all we can do is offer finishers for the two
most common tail pipe diameters and leave it to you to measure your tail pipe external diameter before ordering. Other diameter finishers can be obtained
on request; please contact Somerford Mini with your requirements.
Ill. No.	Part No.	Description	Qty. Rqd.	Remarks

	GEX1830	FINISHER, tail pipe	1	Fits 1 1/2" external diameter tail pipes.
