Left pipe shows richer..
Fullsac and CFR's. SE open filter. Bike runs great.
I have tried stock/XIEDS/PCIII, while all run good, they all leave the left pipe with a noticeable darker inner cap. When warming up I can certainly see a little black puff out the left when revving it. Nothing out the right side.
I even ran the PCIII with 5% rear cylinder trim and it still did it?
What's the deal with this?

It's the stock header with the fullsac trudual conversion. They are cfr slip-on copies. Awesome sound out of these. I have no idea how you would get a set now. They don't have anymore that I can find.

Could it be that one cylinder might be working more in your engine then the other? Just asking?

On my 09 the left pipe is darker as well.It has stock exhaust(MRs still in the box) and motor.I believe it is darker because there appears to be more exhaust coming out of the left side,which is opposite to way my 06 std was.I guess it has to do with the cross over on the 09 and newer bikes.

I do, sorry that's why I asked about the head pipe. The stock head pipe with cat on mine runs richer on the left (or so I think, as it shows black). I'm thinking the stock head pipes which are actually 2 into 1 into 2 let more exhaust out the left pipe. Just my two cents!
