Exhaust pipes are changed on bikes for a variety of reasons; performance and sound are the most common. While most louder exhausts generally increase power, this isn't always the case and can't be assumed. Also, certain exhaust systems that exceed a volume in decibels may be illegal in select municipalities.

Straight pipes are typically found on drag bikes or "hogs" --- Harleys and choppers, for example. These are exhaust systems that have no muffler or baffle, hence the name; they're essentially straight pipes to the engine. These pipes are loudest types of exhausts available as they have nothing in place to quiet the sound. On some bikes, the sound can be so loud that it may cause damage to the ears, which is why some riders choose to wear earplugs. The sound is raw, aggressive and deafening. Sport bikes can opt for straight pipes as well, but depending on the bike, they may actually reduce engine performance. Straight pipes are commonly used on 1000cc-plus bikes.
Racing & Custom Exhausts
Racing and custom exhaust systems are the next loudest. These are exhaust systems specifically designed for a particular model motorcycle and the most likely to increase performance. Often they're modified factory (OEM) exhaust systems that have been tuned or fitted for a particular model. The best and loudest exhaust system is the one that fits the best for that particular cycle. For example, two bikes may have the exact same exhaust system and create two different sounds; it depends on the type of engine and the size. Racing and custom exhaust systems can be found at performance bike shops and aftermarket motorcycle tuners.
It's a general rule of thumb that the stock exhaust on any bike isn't the loudest. Manufacturers have to comply with transportation authority regulations on sound and emissions, and they often try to make all of their exhaust systems comply well within standards. The exhaust system that is the loudest depends on the type of bike and the size of it. Cruisers, choppers, dirt bikes and sport bikes all have different systems. It's best to consult the manufacturer or a mechanic regarding the best fit for a bike. Sport-bike exhaust manufacturers such as Yoshimura, Hindle and Graves all make a mean, loud exhaust. For choppers and Harleys, brands such as Cobra and Bassani are best. For dirt bikes, FMF and KTM are worth checking out.
