Exhaust “Blueing”

Many people who have seen motorcycle exhaust blueing often attribute the discoloration to poor quality pipe material, inferior quality chrome plating, or just some inevitable force we just have to accept.
FALSE!
The Facts:[/b]
[/b]At HackerPipes Inc., we use 18 guage tubing which gives the best flow(least resistance directly out of the head), and the highest quality product.
With quality in mind, we consider our polishing and plating to be far superior to any product lines currently available. Many come at a considerably higher price to the consumer. However, HackerPipes can turn blue as well. Most any pipe can and will. And there is only one culprit…EXCESSIVE HEAT!!
If your bike is mis-timed….too much heat. Run lean? More heat. Run out of gas? (more air than gas)…heat again! In these instances, more air than fuel will result. And with the induction of more air, temperatures can flair as much as 200 degrees instantly; thus frying the pipes. This is comparable to a Blacksmith working with molten metals and, needing more heat, applies the bellows to allow maximum air-flow and flash temperatures.
This is one of the two main reasons almost all manufacturers offer heat shields. From exotic to psychotic, all factory pipes can discolor.
These days, many custom builders and fabricators who specialize in “one-offs” with great expense in time and labor will protect their investments by having the pipes treated with a special ceramic jet coating. This usually is a glass/ceramic base used as an insulation to line the inside diameter of the pipe. This protects the metal from the extreme heat and been proven, depending on the degree of treatment, to be better than 90% effective. HackerPipes Inc. has not had much demand for this application, but it is available upon request at an additional cost to the customer.
Lastly, there are products on the market that the manufacturers claim will remove blueing such as BLUE JOB, BLUE AWAY, etc. that are available at your local m/c shop. Some of these products indeed work to remove the blueing/stains, however the heat damage has already been done, and the stains may resurface quite rapidly.
Here at HackerPipes Inc., we strongly recommend that you treat your new pipes by starting your bike and letting it idle for about one minute, shut it off, wait 15 seconds, then repeat the process 4 or 5 more times; thus annealing the pipes by evenly distributing the heat, while carbon coating the interior for greater heat insulation.

Keep the rubber side down!
