Air, fuel, oil, spark, and hate; these are the things that make a motorcycle run. The last one is up to interpretation, but I've found you have to hate it just a little or it will abuse you. Everything must be in the right balance.
Racing requires exertion. Air intake is important, but that won't serve you well if your machine can't exhale just as hard. I specify racing because the Competition Werkes GP Slip-On exhaust is not for everyday street riding. The complete lack of baffle gives a wide, unrestricted path for your bike's respiration.
The GP is lighter than a stock muffler, and every ounce counts. Increased air flow will lead to increase horsepower, so long as you've got the fuel, oil, spark, and hate in balance. This wide exhaust has a powerful appearance and is hand-welded in the USA.
Constructed from straight-section stainless steel tubing, your bike will get a deep, intimidating sound. It hasn't been coated for the chrome shine that cruisers are so fond of, so it retains a purely industrial street appeal.
You can expect to invest about 20 minutes to go from stock to the Werkes GP slip-on. It is one of the less expensive slip-on mufflers in its class, and riders have been more than satisfied with the performance and sound. For the actual price, you'll have to check your make and model, and you can invest another $100 to make it street legal if you are so inclined.
