Does anyone recognise the make of these pipes ?
Would they be very loud and would my standard bike need chipping if I bought them ?
Would they be a good mod or not ?
How much do you reckon they're worth ?

Sorry to pose so many questions but I've emailed the seller and had no response . I think they look quite good quality and condition and whilst I don't particularly want more performance or noise I would like to ditch the cat and lose weight.
Oh sorry, another query springs to mind, what is the implication for the MOT test ?
Thanks for any imput.

They are Two-Brothers from USA.

The CF weave gives them away.

They should be fairly throaty........

Two Brothers ... pretty good make then.
How would fuelling be affected ?

With the decat and better cans - it will make it run a bit on the lean side.

That may or may not bother you, but if you want to do something about it - there are several options ranging from>

Accellerator module

Techlusion unit

Power Commander

Remap.

These pipes are painfully loud and are a carbon fibre drain pipe.
Unless you want everyone (and I mean everyone) you pass to turn and look at you, then avoid them like the plague.

They are also not road legal and will create issues at MOT time.

Just looked at the ebay pictures and noticed one of the pipes in the picture is missing the connecting band to attach it properly and the original BMW numberplate assembly cannot be used with it. The additional number plate / light parts required are not shown as part of the sale.
