I wasn't sure if you would get the reference to what I thought might only be a comedy on American TV.

Any news on a system for a standard gts? Mine is blowing between the cat and the downpipes.

You can only buy secondhand or repair I'm afraid, no one makes a direct replacement. Several of us have modified FZR1000 downpipes which is quite easy if you can cut/weld.

I can probably lend you another cat, and repair yours short term. I am working in Wakefield at the moment, and am coming from Manchester via M62, but better still I can lend you a cat bypass, as I have a Gazelle 4-2-1 collector that takes the standard downpipes & standard can.

Give me a couple of days, and I'll collect it from the workshop.

Very kind of you thank you. Do you know if the cat comes off with the downpipes in position - I am a bit worried about removing exhaust headers that have been in place for 14 years without snapping the studs or rounding the nuts!

I can meet you anywhere when you are ready.

As far as I remember you can send it backwards, if you remove the rear silencer. There is a possibility an engine crane* might help but we have studs and stud extractors.

Thanks already seen your photos. Will have a go at getting the cat off.

Hi, have got the system off quite easily (except for one nut sheared off). It is actually in good nick except the headers for the downpipe on the cat are totally rusted. I have read somewhere that these are steel but that the cat is stainless. Assume that it needs a specialist welder to fit new headers to the cat?

Is this something that you can help with?

I think that Yamaha made the system in stainless steel but welded it with 'ordinary' welding wire, so the welds rust.
You can cut up some stainless tube and weld them to the cat, it needs tig welding or mig welding with stainless welding wire.
Theres a piccy on the site from someone who has already done it if you search the gallery.

Will see if I can find someone local to do it.

I misunderstood when you said "I can probably lend you another cat, and repair yours short term"

Thought that you meant that you know someone who would be able to do this for me.

Thanks anyway.

I know a couple of people near me, one real close to me :lol:

Years ago, I mig welded one for Dave Carey aka Bear, Rob or Spitmuis in the Netherlands also did his. I did have some stainless tube around cut to length, but it could be anywhere right now.

Oops sorry 24c, I thought that the reply by Daf was your reply.

Did a bit more research on the web and went to a few places in the area. Found a specialist exhaust place that can do it but they dont have the tube in stock. Somewhere else put me on to a company called metal supermarket so will be calling today to see if they can supply the tubing.

24c, any news on a small production of those headers? I want to change the headers this winter, but if you can manage to have them ready before ~February then you've got one extra order :)

I've got some fzr1000 exup headers at home, already did some cutting but can't get them to fit.. seems i've bought just the model that doesn't fit :(

It's a funny thing, the welding guy phoned me up and said he was moving premises, and he mentioned he was still happy to do stuff for me. So I mentioned the stainless steel headers we discussed before, and said I was still waiting.

He's getting in touch with a guy at CCM motorcycles, and I'll be meeting up with the another guy to sort this out... we shall see what happens.

There is a French guy that emailed me on an old hard drive that was keen too, and it is all perfectly feasible still. I even have a pattern collector to take the standard pipes minus the catalyst, but work takes all my time :cry:
