STAINTUNE exhausts are designed to be the finest system available. You should not limit any comparison to just "how much horsepower do I get"? Do you want to buy a new system every few years because the one you bought, that made the most horsepower, fell apart? It hardly seems that any others can be considered comparable or even a value at that point. We have countless customers that find buying the best system once sure beats the pants off trying and buying something cheaper twice, or even three times in some cases. 
 

Mechanically, visually and audibly they are an example of how far a manufacturer can go, without cutting any corners to attain a level of fit and finish that every other manufacturer wishes to achieve. The meticulous hand welds, hand polishing, the use of stainless steel and a packing material that never blows out or needs servicing, gives them a huge advantage over all others. There was a most interesting quote from one of the largest exhaust manufacturers at a recent trade show, "I wish we could do that to our systems, but it's just too time consuming". It's not what they could be doing that is of interest, it's what they don't do that makes STAINTUNE an instantly superior product. The effort alone it takes to polish raw stainless steel to a jewellers grade finish, in no less than a seven stage process, is testament to the lengths STAINTUNE goes to set itself apart from the rest. The materials used have the potential to outlast the expected life of the vehicle. 

Part of the pleasure of owning a premium exhaust system is low maintenance.  STAINTUNE exhaust systems are packed with a spun stainless steel wool which never disintegrates or blows out, and require no internal maintenance. This means you can spend more time riding. 

You also need to take into consideration that every exhaust that STAINTUNE makes does not require modifications to the bike in any manner, such as jetting, chipping or any other change at all. Simply take it out of the box, bolt it on and go! No other labor is needed to make it work. We don't know of any other manufacturer who can make that claim.
