yosh pipe blew up, NMN help!

[BajaRon]

Why the hell would they not cover a exhaust that was made for a vehicle? This is totally my fault for not knowing that the brand new exhaust I have seen advertised on the bike I own is not made for that bike. Also I have not damaged this pipe in a crash or in a race, it was being used on the street and 2 drag nights. Again its a risk you take running a bike or vehicle faster than other people but when I have run other bikes hare its your MOVING parts you check on or worry about.F yosh for not backing there product if they don't, I am still waiting for a real conversation and them getting back to me.

Ok, forget the "Not made for the bike" part. It is an easy out for the manufacturer but is not really the problem here.

I guess my point is that a manufacturer cannot be expected to stand behind their product when failure has nothing to do with their product.

When a product is subjected to conditions that exceed resonable tollerances, there isn't much the manufacturer can do. At this point the user has to take responsibility for the damage.

Your speed isn't the issue nor is the fact that a muffler is not a moving part. Your headlights are not moving parts but if you run 32 volts to them the manufacturer cannot be expected to be responsible for any damage.

I'd say if you get your fuel issues corrected, any quality muffler (like Yoshimura) will last a long time. I've got about 8k on my Yoshimura with no issues and I think Lamont has over 20k on his, and he is not easy on anything.

It's not the muffler.

Well - without an expert from the manufacturer looking at the blown pipe - I'm not sure how you can properly assess blame/cause.

Considering this is the second pipe - I would suspect something wrong with the bike. If it ends up being the gasket or some other BRP product - BRP isn't going to cover the pipe either.

Bummer all the way around.

correct we can specutate all we want but I ran the thing for an extended amount of time at higher* speeds and it was discoloring but was a normal thing, I replace the rivets that held the yosh nameplate on it but it was not cracking or flexing in any areas, this is unlike the Two bros which was was coming apart well before it failed even with repacking and re riveting it twice. I am disappointed it blew and would like to know if it was my use or if it is a metal issue. The main point of this is to make sure that we get to the bottom of what really caused this so nobody else is stuck with questions on what they are getting into or what the risks of running certain pipes and how much they will take.
IF I had read about the issues I have had with the pipes I have had I would be running a two bros dual pipe or a leo vance, they seem to be worth the extra amount of money so they don't go to pot.

So what are you running on your intake side again? Have you checked to see if you're running too lean?

Did you have any problems when you were running more 'stock' items?

I don't think I'd spend more on another pipe until you figure out the cause.

the only thing i had for a mod on the two bros pipe that blew up was a race air filter and o2 modifer. When I got the yosh i put about 3k on it and then got the eviozone race air system, put the o2 sensor and juicebox and have about 2k on it when the yosh blew (about 12k on the spyder when it went) I ran it the same all the time I had it.

this is what I got from yosh, going to talk to them tomorrow.


Seth,

I apologize for the inconvenience, but the fact of the matter is we do
not manufacture anything for the Spyder. The dealer must have taken a
Yoshimura muffler and found a way to custom fit it to the Spyder, and we
do not cover custom applications under warranty. I would suggest taking
this up with the dealer whom you purchased the system from.

True, I am certainly not the final word on what is causing the problem. A bad gasket may be contributing but not sufficient for this much damage in this short of time, I don't think.

Still, the facts are that 2 good quality pipes have failed catistrophically in a short time with no external cause. There is really only 1 way this could logically happen and that is ignition of raw fuel inside the muffler.

If there is any other plausable cause I'd like to hear about it.

And, if this is the case, the manufacturer and their product is not the problem.

And you're right again, it is a bummer. I'm just hoping to save him a 3rd muffler as this will surely be the result again if the problem is not fixed.

Not surprised, this is what you will get from any manufacturer for just about any part where the application is outside their published specs.

Hopefully, they can take a look at your muffler and give you some direction on what is wrong and how to fix it.

There is no doubt that the Spyder is hard on a muffler even when everything is right.

ordered a leo vaince from eviozone, the only pipe really make for the engine, bigger pipe diameter AND if I break it he I will be the first one according to ken and he will send me a new one. Wish I would have known that the two bros pipe was a very poor design for the spyder and they will admitt it does not work so they only sell duals for it AND that yosh does not really make a pipe for the spyder and it is just retro fitted on there.
Again if I would have known this information i would have spend the exta money for a pipe made for a big twin and would stand being their product.

The piece of S two bros single I welded the back cap on blew part on teh front and I re riveted it with bigger rivets which some of which are pushing out, I am welding the back of it, so both ends look like they have some kind of STD.

Wonder how the other guy on here that blew up his yosh faired.. I am sure he drove his spyder "too" hard and it was not that it was not designed for the bike it was the "mods" he did. 2 out of 4 owners had problems from what I have read on here 50% hmmm. I sure others have the yosh pipe on here its just what I have read on this thread. Tear away kids.

I hope you have great luck with the V&H pipe. Please post how it all works out.

It is very odd to me that Yoshimura (an others) make cans specifically for the Aprilia race bike that runs the exact same Rotax engine (except that in those applications the compression is about 10% higher and it puts out about 30 more horse power than our de-tuned Spyder motor).

You would think those applications would see more stress/heat/pressure, etc., than they ever would in our Spyders.

Not sure what you mean by "2 out of 4 owners had problems". You don't mean Yoshimura do you as I am sure there are many more than 4 Spyderlovers running the Yoshimura cans.

Otherwise, that would mean Lamont and I would be the only 2 who have not had issues with ours and that can't be true. We do have (combinded) at least 20,000 miles on our Yoshimura pipes. We don't drag the 1/8 or 1/4 mile but we do ride pretty hard.

Hope the V&H fixes your problems and lasts you a long time.

Good Luck with the Leo --- Ken sells some great stuff and really knows these engines.

That being said ----- my money is on that you will have problems. The only common denominator to your pipe failures is your bike. Before you blow another pipe - I would have the whole system checked out.

Let us know how it works out...

Maybe too early but just curious as to how this is going....Have you received/installed this pipe yet?
