Default Borla Headers Causing RHS or LHS to go lean?

Someone was telling me that running borla headers will cause one side of the engine to go lean while the other side becomes rich. Personally I'm sceptical because I've never heard of this and I doubt they'd release them to the public if this was the case.

Has anyone ever heard of this happening?

Hmmmmm.
I never heard of that, what is the reasoning behind this?

The reasoning, perhaps the length of the runners. I'm as much a sceptic as anyone. I'd rather not say who mentioned it as he was merely passing on something he'd heard.

I had mine installed at LaChute Subaru in Quebec and Rejean went way out of his way to stay late and do the install for me (personally). These sorts of things explain why I drive 120km out of my way to have the car worked on.

Anyway, back to the headers, they're quite loud. We put on new gaskets so I'd be surprised if it was a leak. Quite a lot more power! I think that my poor fuel system has probably reached its upper limit and as such will be installing a TecII ASAP. Certainly before I replace the heads/cams.

I've got the borla headers, 2.5 catback N1, and an intake.

the fuel system is doing just fine though.. I can still get it running rich wherever I want using the S-afc.
