Choosing an Exhaust – Is That Full System Really Worth It?

How do you choose an exhaust system? The answer may not be so simple.

Before you rush off and purchase the most popular brand’s exhaust or the one your favorite racer endorses, you may want to consider the following factors…

COST VERSUS PERFORMANCE

The first question you should ask yourself is: Do I want, or need a half system or a full system? Now please note, all half systems and all full systems do not follow the same rules, but there are some general guidelines. To start, a full system will commonly set you back twice the amount of cash of a half system. And you will not usually reap twice the benefit…

  • Full systems typically replace the entire exhaust, from the header pipe connection (where the exhaust exits the engine) all the way to the final outlet (either under the seat, beside the swingarm, or underneath the motorcycle).  Full systems may come with baffles to reduce noise (“dB killers”) and on certain makes and models may come with an ECU for changing the fuel metering/mapping (such as (Ducati with Termignoni & Aprilia with Akrapovic).
  • Half systems (or slip-ons) normally replace the exhaust end-pipe only, while commonly replacing mounting brackets and bolts under the tail or beside the swingarm and pegs. So why would you replace only the end-pipe? Because it may be expensive and unnecessary. Many modern motorcycles have an efficient, well-manufactured header pipe (some even made of Titanium, which is what the high-dollar aftermarket pipes commonly market). One of the only considerations to upgrade to a full system is if your header pipe includes a heavy catalytic converter which blocks air flow and decreases power gains from just a slip on system. Another consideration is if you are racing, going for utmost lightweight, bigger diameter pipe with literally a couple more percentage points of horsepower. Most people are just better off with a slip on pipe. (Note: Slip on systems may also include an ECU for mapping and dB killer baffles depending on the make and model)

The good news is slip on systems often increase performance near full system gains
