Exhaust replacement on FZR600

[JodieWodie]

My exhaust pipes are very rusty underneath, (in middle of belly pan),.. and they are getting worse.
More worrying, I have noticed a hole appear today, about the size of my small fingernail in one of the exhaust pipes. There has been a bump to it at one point, and now it has corroded through.

I understand this is making the exhaust noisier.
How dangerous is this ?
I do plan of replacing it asap of course.
How much would the replacements be ?
Does the whole exhaust system underneath need fixing, or is it done in sections ?

Thanks so in advance,

JO xx

Hi

Not sure it is, but assuming it is virtually the same as my older FZR600.

The exhaust is a one piece unit from the cylinder head back to just behind the footrest hanger, with the remainder being the silencer. Held on at the head (8 bolts / studs) and another bolt under the back of the engine, then they attach to the silencer section with the silencer bolting to the footrest hanger.

Think D&K sell replacement exhausts but not sure they fit the FZR600R. They are around £200. Micron do a complete system but that would be around £400.

All the best

Thanks KS..
the silencer is new, so that is okay.
It's just all the pipes that are rusty.

My b.i.l is a whizz with bikes, I just hope he can find one that fits and fit it for me
I will try and get hold of him.
We have looked through the manual ourselves, and it looks like a simple job written down

A set of Micron Delta pipework will cost around £250 according to this website. Not a bad price for a stainless system made by Micron, but still not cheap.

Personally, I'd get them repaired. If its not a big hole and in a state beyond repair, it might be worth spending a few pound just taking them to a local workshop who can cut off some of the rust and patch it up.

Then theres always phoning a few of the bigger breakers yards, try source a set of standard downpipes off a broken bike. Again, a little cheaper than buying a new set, but at least with a new set, you know you're getting something decent.

Shouldnt be too hard taking them off, just as long as you're careful not to snap a bolt in the cylinder.

Thank you Keith,
Very helpful

Am starting with breakers, ..may think about a repair until a set comes along as there is only a small hole and some rust.

Hi

Looking at the pics I suspect the Micron pipes will not work with the stock silencer, so you might need to add £150 for the silencer to the £250 for the down pipes.

All the best

You'll get second hand good condition pipes for about £50 on ebay. I've been looking for a set for my FZR750 for months and they are RARE for the 750. I got some last week £90, yeay!!! I'd been plagued by 600cc ones going for pennies and seeing none to fit mine.

The 750 pipes are all in one piece, can and all
