FMF Q4 Exhaust Install question

I recently purchased a 2008 KTM 990 Adventure and purchased the FMF Q4 exhaust to slip on. The pipe connects to the stock mid pipe and I am assuming you are supposed to use the metal gasket in between the slip on and mid pipe, similar to the stock exhaust. In any case that is what I did. After installing and starting the bike I felt around the area where the slip on bolts onto the pipe and felt some air coming out. I am not sure that this is supposed to happen. And I am geussing that it is not. FMF web site us usless for information. Anyone who instaled this pipe before have any suggestions or wisdom? I really appreciate it.

If I remember right you do need to use the brass gasket, and it is based on compression so you may need of new ones if the old are too deformed to make a good seal. They should not be leaking anywhere in the system. You could try and loosen the bolts and tighten them as even as possible and see if that helps.

I started on the right and it was a pain in the ass. Of course its my first time installing them. The left side went on real fast and seems tight.

Is there a tried and true method for testing for leaks?

I just did this recently on a '10. Be careful about over-tighenting or you risk deforming the flange. FWIW, I had some high temp silicone that I had from when I got a Two Bros pipe. I applied that to both sides of the metal gasket.

It's plumbing #101.........loose as a goose.....tighten at your own risk.....let a few cycles of expansion/contraction occur before tightening and a bit of expansion sealer is a good thing.........JMHO..........

I just finished installing some scorpion exhaust on my 9fitty, and I had to fabricate some gaskets from a sheet of hi temp gasket from napa. Seems to have worked like a charm.

Where might one find the high temp silicone? And also to the other party what type of gasket material did you have?

It also appears from the stock cans that the 3 bolt piece that bolts the two pieces on is flat when it is fully on, and on the new exhaust it is not although it is on tighter than a drum

Sounds about right, 209Ninja. Same as mine.
Don't forget to tighten the rear mounting bolt and have the can fall 1/2 off in the middle of no where like i did. Stupid!

Thats funny. I thought that might happen to e if i didnt pay attention. I am going with the silicone recommendation and I think that should do the trick.

Just about every 990 installation I've been a party to needed a) new gaskets, b) a healthy whack to seat the pipe on the header properly and c) a bit of high-temp silicone. Seems as though the gaskets like to be one-use-only unless you want to use a lot of silicone.

I just installed a pair of FMF Q4s on my '11 990, and am experiencing the exact same thing - no air leaking on the left side, but can feel some leaking from the right. Bike is near new, so I thought I could use the existing gaskets.

I also noticed that while the stock can header ends are flat, the FMFs are not, and hence the seal is less than ideal.

I'll get some high temp sealant, and see if that helps.

Q4 problems

I like my Q4s but they did come from FMF with one of the nuts misaligned. I sent the can in question back and they re-welded it. After that it is all good!

FMF (low quality) weld issues ?

I too have had some poor quality welds from FMF :-(

Although this was on a powerbomb header (on my 690) - one of the heat shield mounts fell off, leaving a 1" hole !
I returned the pipe (had to pay for shipping one way), and instead of replacing it, they re-welded all the mounts - likely better than new (if low quality welds are the norm). Customer service was polite and efficient.

I'm hoping perhaps they'll take note, and improve their quality.
