Fmf pipe crack at the weld.

It’s two years old bro. Get over yourself and buy a new one with the very generous discount they offered you.

I would just Just bring to a competent welder,when you mount pipe & Silencer , start tightening from front mounts to rear, making sure no binding at any of the mounts…. Not saying you did not have it mounted correctly, but sometimes if pipe & silencer are not allowed to kind of float within the rubber mounts, unnecessary pressure points can creat cracks..some pipes are just prone to cracking, like ktm 250/300 lower pipe mounts…. Of course would have been pretty good customer service for FMF to say : send that pipe back to us, we will weld that up or exchange it out at a discounted rate or something along those lines….I know welders that would gladly fix that for a  12 pack of good beer, probably even reinforce that area…. Welding is fun

Have someone fix it..I done this 100 times before..with cr80 pipes....lasted long and was free most the time.  

That's not gonna pass sound test.

Now it's a crack pipe

Ya but have you seen all their new t-shirts?

I have never seen a broken FMF two stroke pipe before. 

sure the pipe is two years old but even a blind person can see that it has lived an easy life. Not dented, not blue in the plating shows that it has been ridden on low rpm’s etc.

I don’t know how big the discount they offered were, but in a case like this they would have more to win by giving you a new pipe as a good will.

I had a Renthal twinwall that the outer wall cracked on in 2002 (without a crash) Renthal gave me a new bar and took back the cracked one. 

Fmf should do the same. Sure they have a 1 year policy, but look at the pipe how little it has been used to.

Just have it welded and move on. 

I've got a whole box of FMF pipes that have cracked at the welds that I had repaired.  The cracks are where the bracket goes and on the center section though.   I've cracked a bunch of fmf stuff over the years and don't bother with them any more.  It's part crap welds and part poor fitment putting strain on the welds.

I bet if you called into Pulp when Little D was on he would have said he'd send you a brand new one, no problem. Because clearly he is all about public perception of the brand right now, considering all the ads and t shirt sales they are concerned about. Too bad on the back end you're told to give them more money....discount or not, they are still trying to make a profit off you twice. T shirt sales must be down...

I want to like FMF. But I have seen too many failures due to cheap material in recent years. Buy another brand and hope they get their stuff together. If you break anything in a crash… well, that’s the nature of the sport. But failures like the one above just aren’t acceptable, particularly when that pipe looks near new…

Have been using PC stuff exclusively for 15+ years on 2 stroke. No failures. Lots of other good brands out there. But FMF needs to get their QC together IMHO. 

Not replacing the pipe outright because of a manufacturing defect is just awful customer service. Take your business elsewhere. 

HaHaHa,Perfect!

Had it happen to two on my sons super minis. The first time it happend i dcalled FMF and got the same answer you got. I just order a new pipe then a year later it happed again. i was told that is very common on the supermini pipes???? i ended up gettting them both welded and had a spare. 

I had the same problem with Pro Circuit YZ250 pipe that cracked everywhere.  Called them to send it back so they could see it.  They told me to pound sand! 

Welded, rewelded and it kept cracking.  Piece of junk!

I have bought several FMF pipes and never had an issue!  Will never buy from PC again!!

Strange it had been cracking long enough to crack all the way around it. Didn’t you see it or hear it before? Oil leaks from it?

I would check the subframe for being bent applying pressure to crack the pipe.

Pipes have multiple mounting points and a new pipe has to have all points and brackets loosened enough to wiggle the pipe around and align it at the cylinder then tighten.

Cracked next to the weld, not on it. I think this is typical if the weld overheated the metal, makes it brittle. If you have someone repair it just know they'll have to remove the nickel plating so you either need to replate it, or paint it to keep it from rusting. They'll probably insert a sleeve so the inner diameter will be slightly reduced but I doubt you could tell a difference.

Yes, this was a common problem on the YZ85 pipes in the past couple years. FMF started fitting a gusset at that joint. In our case they were fine until they weren't. Didnt start as a small crack

They all do it. PC & FMF. I ride 450s but the headers seem to crack way before i'd like them too. Ti ones are way worse. I actually switched to running stainless headers with Ti mufflers. The stainless headers hold up to a significantly higher number of hours & i have more confidence in them in the off road races. Also much easier to find a welder to weld stainless if need be. Which i've only had to do 1x with a ton of hours. 

Same here. Earlier this year my R304 shorty on my 125 broke right at the mounting hole while I was riding single track. I took a picture and emailed PC asking if they could sell me just the mounting bracket and I could have a buddy grind the old one off and weld the new one on, I wasn’t expecting shit since the silencer was nearly 8 years old at this point and I even mentioned my original purchase date and how impressed I was it even lasted this long. The gentleman who was handling my emails shot back and said they didn’t sell the bracket, but he could give me a deal on a new R304 that was half of what Rocky Mountain had it listed for and a few bucks less than my cost when I worked at a shop through parts unlimited. I really felt like a valued customer there, and it solidified that anytime I’m looking to purchase an exhaust I’m going straight to Pro Circuit.

I run PC pipes and get about 60 hours out of a pipe before it cracks at the second bend on both front and back. Neither part is where a weld is. A lot of people don't understand metal "Work hardens" from the heating and cooling over time and the vibrations. That makes the metal brittle and likely to crack. I weld them up and get about another 10-20 hours before it cracks next to the last cracks, maybe 1/8-3/16" away.

Welds, blown out dents and blueing are badges of courage for 2T riders…

Put a Bills Pipe on that RM

This is the only true pipe for an RM

I had the same problem on my RM125. This is a Scalvini and it broke at the same spot landing from a jump. Must be a weird stress point, I added a brace similar to what PC used on my 250 pipe.

Had a power bomb header crack on the weld at the top of the bomb. Sent it in and it came back welded. This was back in 08 or 09 on my 2007 KTM. It’s still going strong but the bike doesn’t get used much. 

 

If you find someone to weld repair it....ask them to "gas" weld it...not electric wire....the process will "anneal" the old weld area and the heat affected area that actually cracked in the first place...clean the carbon from the inside before hand as well....

How many oem pipes do this?

OEM quality is usually much better than aftermarket, it's why OEM is more expensive. FMF and Pro circuit Could make higher quality stuff, but it would cost twice as much.
