I just wish someone made a pipe that does have so much of an upward angle to the can. Some of them look like they should be a mortar.

Here is a picture of the Corsa from Leo Vince.

Here is a picture of the GP One slip on's that I feel look way better. I wish Leo Vince would make a titanium full pipe with this type can on it.

Hard to for me to buy a pipe that is so fugly. Nice to have the weight reduction and more ponies but most of the pipes I have looked at look like you are out duck hunting or something.

FMF! Love mine!



The Vance and Hines Urban Brawlers look good too.

cars and motorcycles that meet smog requirements run pretty lean at idle and cruise speeds. but under full throttle [ open loop] they all run a little rich to protect the engine from pre ignition. a full system might lean out some of that rich condition under full throttle, but i doubt enough to hurt the engine.
this is not science but for some reason a less restrictive exhaust system many times does not lean out the idle and low speed A/F ratio. my 04 Z 1000 100 % stock after a full MUZZY lost about 2-3 MPG [ richer]. i am never going to say do not install a PC and do a a/f check. that would be foolish.
but i also feel from 40 years of playing with motorcycles that just a exhaust system will not screw up your engine. if my ZED started running bad SURGE, HESITATE,POOR THROTTLE RESPONCE OR A BIG SWING IN FUEL MILLAGE i would do a PC.
my bike halls ***, gets steady 40 MPG and just has spot on driveability. a
pc is just a tool. some need it some do not. your A/F ratio on a new bike is not close to perfect. lean down low and rich at full throttle. all a PC does on a dyno is lean out the mixture under full throttle to gain some HP nothing more. if a dyno operator leans it out too much to give you a nice HP gain it is more dangerous to your engine than if you left it alone.
this is my 2c worth. if my post makes you think outside the box i am happy.
i have a victory motorcycle also i ran it for 2 years with a very modded exhaust without a PC. it ran fine. it was leaner than stock becouse my fuel millage went up to much. after 2 years i added a S&S air system which really woke up the performance. at that time i had a performance down load put in the computer and it needed it for sure. some bikes you can do a down load to the stock computer which does about the same thing as going to a PC. it re programs the A/F ratio. with a PC you can change the settings. with a down load you can not.
