Front Exhaust Down Pipe Sheared - What are my options?

On my way home from work tonight my exhaust note on my 2001 VFR800Fi1 changed for the worse.
When I was able to look at what had happened I found that one of the front exhaust down pipes had sheared completed due to corrosion.

What are my options to sort out the issue?

Are these sections of pipe available as a part or am I going to need to replace the entire system?

Thanks in advance for any help.

 

Wow, Im interested in a picture of this. Havent seen a pipe on a bike rust (or corrode) all the way through before, especially on one after the 80s.

Is it right at the flange near the engine or is it where the pipes Y into the cat?

 

Try Ebay

 

Here you are, hope it's clear to you.

 

I guess either one of these will do the trick.

Interesting picture. I wonder if all of the pipes are about the same. Joints probably corroded too. I would go with a new complete exhaust system. My 86 still has a shine on the pipes. Wonder if Honda cheapened the design over the years.

The rear pipes on mine need to be changed with the engine out. Gets complicated.
Good luck.

 

Holy hell! Guess the UK has much harsher winters than we do over here. At the very least, cut off the front two pipes and see if an exhaust shop can fab up the couple of bends you need. But it would probably be easier to get a whole new one. Dont know which option would be cheaper though. Also depends on if the flange and bolt/nut can be saved. Otherwise you might have to have a place remove and/or retap the bolt holes if you cannot do so yourself.

 

common problem in areas with high moisture and salt content in the air. I see similar in FL all the time near the coast.

you need a new exhaust system.no ifs ands or buts. if that looks that bad, chances are VERY good the rest is not far behind, and is ready for a scrap bin.

 

It looks like that has been leaking for a long time. The material around it is very corroded.

 

Delkevic? Just an option.

 

Okay, I have managed to remove the front section by cutting the pipes lower down. One of the studs broke as I went to undo it, but 3 remain.

What can I do to remove this stud?

 

If its level with the head, you could try an "Easy-Out". It's kinda like a backwards drill bit, you drill a hole in the stud and thread it in, I think they have a LH thred arrangement that loosens as you tighten (sorry, it's hard to explain). Obviously lots of penetrating oil for a few days before. Sorry to hear your woes man, of all the things I hate working on exhausts top the list!

 

I am sure the problem that occurred to the steel pipe has also corroded the studs into the aluminum. Make sure you use plenty of penetrating oil on all parts. I have solved broken studs and bolts by welding on a bigger nut to the stud, gives you something to grab onto and the heat from welding helps. Maybe Donald B will speak up.

Glad that welding on a nut has helped someone else. The heat of welding seems to really help.

 

A friend of mine with a lot more experience with this kind of thing came over today. He used a little bit of what he called "percussion" (basically hitting the end of the stud fairly hard with a hammer) and a good set of mole grips. The stud came loose then after a lot of wiggling back and forth it came out.

Now I have all 8 nuts off the studs off the front and back pipes the only thing holding it on is the bracket on top of the catalytic converter. This fixing is unrecognisable as it is so rotten, so I think I'll be drilling that out soon. The replacement unit doesn't have a cat so I shouldn't need to reuse the bracket anyway.

It is always a great feeling to get a broken bolt out. Good luck with your new exhaust system. Probably will run a lot better.

 

I have managed to get the rest of the system off now. When separating the Stainless Steel Tail Pipe I noticed a section that underneather the clamp that has totally rotten too, and this left a jagged edge on the stainless section. I am now wondering if I will be able to reuse the Tail pipe.

Any thoughts?

Can I use this?

 

WOW!!! I have not seen a rotten pipe like that coming from the block eva!!! They do have a tendency to rot out at the collector and I have sold many pipes that rot there, but not where yours disintegrated. I live in south FL and we do have salt air and chit but holy crap!!! dah UK must salt dah hell out of the roads there, I used to ride 12 months up in NJ and had road salt and never had any thing like you had.

When you get everything fresh and all you need to wash your chit after you ride in inclement weather :smile: and use some WD40 on ur pipes or its gona happen again.

 

Man that is hard core corrossion. $900 for full delkevic set. $400 for just headers.

If you could get 2nd hand oem stuff off flea bay that might be a cheap option. I'd sell you my oem headers but the freight would kill you..
