Why are my exhaust headers glowing red?

Our stainless steel wall is only .028" thick and it is completely normal for the header tubes to glow a dull red in low light with the bike idling. There is nothing wrong with the motorcycle or the Brock's Performance mapping developed for use with the pipe.

During aggressive operation; such as wide-open throttle on the dyno, under load from an eddy current brake, etc., the header pipes may glow red for 6-8 inches.

That being said, our exhausts come with PAIR valve (emissions) block-off instructions. If the PAIR is not properly blocked, the pipes may glow red more than normal. Please go to our installation instructions page to find the instructions for your make/model/year - Click here for PAIR Instructions

Also, the bike's idle speed should be set to the manufacturer's recommendation. Typically in the 1100 -1200 RPM range, an exceptionally high idle can cause an excessive glow.
