Hi,

I put my slip on FMF Q4 directly on the stock header without any gasket (the same way someone did here on the forum: https://www.kawasakiforums.com/forum...-review-35228/) but I can hear a little whistling noise coming from that connection.

Does anyone here uses a specific gasket (similar to the one that was in between stock exhaust and stock header)?

Thanks for posting links and pics.

 

I recall someone's suggestion to use the high temp gasket stuff, red. If it's not sealed well, you may get some decel popping.

 

Just fiddle with the clamp till you get it to stop...the Silicone will just burn off,when I put mine on I had to re-position it a time or two,tighten it up good...

 

Thanks for the advice azdeuce, i will try that toorrow.

 

I used high temp silicone and mine is holding good so far

 

The instructions that came with my Q4 said to use high temp silicone. Did you read your directions? I used the copper colored permatex, and it stays intact, no burning, or melting. Clean the pipes with alcohol before using silicone, and let the bike sit for a day afterward to let the silicone cure.

Yep. High-temp silicone.

I thought I had some laying around but did not, so I installed it anyway.

Exhaust leak.

I picked up some black high-temp and R&R the muffler...perfect. (Although the black high-temp did smoke a bit, that copper stuff may be the way to go.)

 

Does the slip-on end up welded to the header with the silicon after a while? This is something I am trying to avoid...

 

I used the ultra hi-temp copper stuff from permatex when I installed my Q4. From past experience with other applications I don't anticipate any troubles sliding the muffler off when the time comes.

 

I wouldn't anticipate a problem removing the muffler. The cured silicone feels kind of like rubber. I peeled off the excess and it didn't stick to the steel of the header at all. Worst case, a couple whacks with a rubber mallet should loosen it.
