I have the Termi high pipe installed.
Turning on the ignition I have EVO 1 displayed which indicates that the up key map has be successfully installed......However,I get a lot of backfiring and popping and my exhaust header pipe is blue which indicates running lean and hot.
My question to high level Termi owners,what is yours like?

In 35 years of riding I don't think I've ever owned a motorcycle which didn't blue it's exhaust pipes. Double skinned ones took a little longer but still coloured up eventually.
Phil, we're not talking about a 30 year old carbed bike here. If a modern bike with FI, and stainless exhaust is blueing then something is wrong

My high termi doesn't pop or backfire often, only when I do something extreme and abrupt with the throttle. My header pipes are not blue, just sort of gold. I'm thinking you have a problem, Dave, maybe an air leak?

My header pipes were bluing at around 300 miles on a completely stock bike.

Here's a picture I just took at 967 miles, the bike is still stock apart from a G2 throttle, and runs perfectly well.

If the correct map was installed with your pipe, shouldn't "RACE" be displayed on the dial?

That's for the Termi Race slip-on. The high pipe displays EVO 1.

For those complaining of popping and banging, disable your SAI. I've put on a few hundred miles so far, and the difference is huge.
Thanks, AH.

I didn't know if the high pipe had a Cat or not.

I have the Sport Termi on my Classic and am experiencing a lot of popping and barking.

How do I disable the SAI?

How to Disable the SAI

Please be advised, this will not totally eliminate "popping" on a setup where the CAT was removed, but will reduce it significantly.

A remap will do a much better job.
Sorry about my last post.

There is already a detailed description on how to do this from tonyjuliano.

Thanks, Tony!

That is what I would term "moderate blueing" - shows you how lean the stock bike truly is. The original poster described a much more severe condition.

Here is what the header should like like - with proper fueling...
