Ben H · 11. November 2006

I am looking for a pair of used cat pipes from an 840 as per items #1 and #2 in the link below.

The cat bricks can be in any condition -good or broken! So if anyone has replaced them recently and has them lying around I would be interested.
Part # 18301742332 and 18301742331.

Thanks.

Hi ben ,my curiousity has got the better of me,what are you planning to do? whats wrong with your pipes ?

I may possibly have two for you mate. About four months ago I replaced them with straight stainless steel pipes but left it witth the company who carried out the work. I will ask them and see if they still have it laying around somewhere as they were supposed to keep them for me.

If they do then you can have them for free.

Thanks Bimmerman that would be great.

I wish to fabricate up a pair of stainless pipes using the flanges and lambda bosses from the original part. This will allow me to easily change between de-cat and cats.

How do you find your de-catted system? Much noisier? Better throttle response?

Cheers
Ben
