This weekend, I've cracked my 4th pipe already on my 250 SX. Its a 2013 (2013-2016 model year). I either crack them right at the bend where they mount to the frame or just blow a hole in it. Both happened twice, so four times total. I tried numerous of pipes including the stock pipe, two KTM Powerparts pipes and a HGS pipe.

Are there others here that have this issue? If not, what pipe do you use? I tried FMF but it's kinda "banned" here due to it making too much noise, so only rode with that once.

I'm kinda tired of blowing my money on pipes.

Are you bolting it directly to the frame? The 2 strokes ive had in the past had rubber dampers between the frame and pipe. I could see bolting directly to the frame being too violent for the pipe

Put the FMF pipe on with the stock silencer.
Or for a heavier gauge option run the PC 2 pipe for the 300,

I use rubber dampers, although there's still a lot of stress on the pipe. I had one pipe that was a perfect fit, but that one got destroyed in a crash sadly. I bought two of them and the other one is a totally different fit which baffles my mind.

I'll try to see if a FMF/stock combo will pass decibel regulations.

Had a 13 250SX that the stock pipe got small cracks around the spring mounts. I got a PC pipe and never had a problem.

Before the 13 the last 250SX’s I had were 00 and 01....both got similar small cracks on the header area of the oem plated pipe. I think the stock KTM pipes are just crappy. I don’t know about the newer ones but the older bikes used 3 springs and MXA used to say to take one of them off to help with the problem.

The stock pipes are made of thin crap. Mine cracked right away on my 2013, I got a Pro Circuit pipe and silencer and that was fine, never cracked.

Possibly something is wrong with fitment causing extra stress or a combo of that and a lean condition creating extra heat as well? Good luck
