| Posted : 07 Jul 2013 - 01:41 Post title : Yellow pipes | | Sorry if this had been asked before. I tried searching the site but kept getting timeout errors.
So, I just got back from a 200 mile trip and notice my left header pipe yellowing. I read somewhere that this is due to a lean or rich condition. Has anyone experienced this?
My Setup: Storm 2013 Cat delete (elbows) UNI Filter Stock pipes OEM TORS Map (20363) 89 octane gas.
Thanks all!

So not relaed to cat removal. I ask Triumph to take it in garanty but they refused. No increase since that time, even after I remove the cat to put the hogslayers and K&N filter (with the appropriate tune).

OR, you can try a different type of gas.I ALWAYS run high test and have discovered that mine loves the Shell 93 Octane.
Now if you've altered the system in some way,or have the machine set up for balls to the wall performance,then all bets are off as it now becomes "trial and error" in an attempt to correct the condition "IF" it can be corrected at all. I wish you gentlemen luck!! Dave!!!

| Posted : 08 Jul 2013 - 09:39 Post title : Re: Yellow pipes (Re: BizRider) | | Regardless of which color they are, a header turning color on the bird is a sign that the internal wall of the header is touching the outside wall and you should have your header replaced. I wouldn't tend to trust the particular color of the header as meaning anything since it is a double wall design. The double wall is going to change the temp that is getting to the outside wall and therefore change the color the pipe changes and therefore make the particular color an unreliable measure of what (if anything) is going wrong. But, the fact that it is changing at all is a sign that the header itself is defective.

| Posted : 08 Jul 2013 - 13:54 Post title : Re: Yellow pipes (Re: BizRider) | | I had the same, left header going yellow/golden. Got it replaced under warranty. As Thatch said, these are double skinned, and shouldn't discolour.
| I won't believe it until it has been officially denied.

| Posted : 08 Jul 2013 - 17:02 Post title : Re: Yellow pipes (Re: Thatch) | | Mine (left) has been discolored for a couple of years now, but I don't think it has anything to do with the wrong mixture. Like Thatch said - they are double-walled so all bets are off.
I thought about replacing it, but hey they are almost impossible to clean anyway so I said screw it (for now).
