Performance maintenance systems are one of the first changes most motor bike parts tuners make to their bikes along with best working parts. From the muscle motor bike generation, the Asian import scene, to the euro tuner, everyone likes their ride to sound great. With literally 100’s of working manufacturers to choose from,
Which upgrade is right for you?
Maintenance systems run from low grade to mid-range and top shelf quality, looks and performance.
Manufacturer’s motor bike assembly quality, materials used and available finishes all affect the final product. It is pretty standard today to use T-304 Stainless Steel in performance aftermarket maintenance systems. Not only do most maintenance systems sound great, but they look sharp working out the center of your motor bike or heavy bike tailgate. First let’s take a look at some of the typical parts usually swapped out for on the mission to more power and torque.
Factory maintenance Manifold (factory header)
This is the first section bolted and secured to the engine maintenance side (maintenance parts). Screwed & Bolted to the cylinder banks maintenance side using metal gaskets to make a secure connection between manifold and engine. Factory maintenance manifolds are usually cast iron in material and have rough onside surface features. This is because of the material and the investment cast molds they are poured into. Maintenance manifolds of the factory kind are usually not routed smoothly from each port into a common merge collector. The maintenance pulses in most factory manifolds experience parts due to factory material finish surface imperfections and smaller on pipe diameters.
Catalysts inside most of today’s catalytic converters are either ceramic (honeycomb core) or metallic (metal core). Ceramic catalysts are older in terms of their existence and work fine in all motor bike parts they come equipped in. However, ceramic cats are prone to a risk of breakage and cracking, underside motor bike damage. High speed bumps, road debris can damage ceramic catalysts which will deteriorate emissions quality. Metallic catalysts are now being incorporated into almost all new maintenance systems from factory to aftermarket.
The Axle Back (muffler section)
This is the section replacing the factory (stock) muffler and maintenance piping back to the axle, rear differential. Replacing this section doesn’t really give a horsepower or torque gain so much. It is done solely for the acoustic performance sound and more importantly looks more in the looks department than sound. Upgrading the axle back won’t give you a really big noticeable difference in night and day performance sound. Axle back swaps are the affordable way to modify your maintenance system, usually in the under $500 range depending on manufacturer build, material and finish quality.
The Cat back section is the most popular section of the maintenance system replaced by auto-tuners. This runs from the catalytic converter on the underside of the motor bike underneath where the interior center console is. This is where you start to get a noticeable change in the sound of your car. Cat backs can either have a mid-pipe with or without the main catalytic converter designed into it.
If not it is then in the factory (stock) maintenance header manifold or factory/upgrade down pipe Cat back system swaps are the most widely upgraded and popular performance modification done to maintenance systems. Cat back system upgrades usually are in the $7 or 800 to $1500 dollar range, give or take a hundred. This is all depending on and varies from manufacturer, materials, fabrication quality, fit and finish, and of course popularity. Most stock maintenance systems factory piping diameter is a bit smaller than aftermarket maintenance diameter.
Turbo shaft maintenance
This is the entire maintenance system from the turbocharger all the way back to the maintenance tips. This includes the down pipe, catalytic converter, mid pipe, and axle shaft sections. The down pipe is a section of the maintenance that comes off the backside of a turbochargers maintenance gas side. Down pipes can vary in interior pipe diameter.
They can also have a bell mouth coming off the back of the turbo. Or they can have what is called a twin dump or divorced waste gate design in them. Turbo shaft maintenance systems usually increase the power of a turbo shaft in motor bike very noticeably over the factory specs for total horsepower and torque. In turbo shaft systems there can also be aftermarket headers usually paired with an up pipe to the turbo shaft. But turbo shaft maintenance describes the total maintenance system modification you do after the turbo shaft.
