RE: exhaust question

I'm sure this question has been asked before.But i'm gonna ask again..What are the actual h.p benefits gained by installing a slip on or even a full.. I'm not much of a mechanic but i remember when i put a full cat system on my lude i only got like 2 possibly 3 h.p out of it..Is it different on a bike??? Now another question.. I was having a conversation with my brother-in-law and he said since my bike has fuel injection it really wont matter if i put an exhaust on it...Now thts somthing i had never heard before??
I know many do the exhaust thing to get that sweet rumblin sound but as far as a performance mod is it really worth the $300++?? Sorry to sound so mechanicaly stupid, but if ya dont ask.....Thanks

Slip-ons don't really add anything, maybe if you're lucky half a horse power if that... A full system can add a few though, in combination with a PC and some tuning.

my 1000RR gained 11 whp over the baseline with an arata map
and since i havent had my 600RR custom mapped yet i will have to go by the other dyno charts i have seen.
akro, leo vince, arrow, have all given 5-6 with a custom map

benefits
slip ons tend to increase hp on the midrange which makes it a better choice for a street bike
full systems give its power on the top end
for example the sato full system gives really high top end numbers but the sato slip on actually produces more hp in the midrange than the full does.
and yes because it is fuel injected it is actually easier to tune than a carbed bike. especially the ones that do not have an 02 sensor. normal non EU spec bikes run specific fuel tables that add or subtract fuel based on rpm and throttle position (air temp also plays a part) a powercommander can alter the oem programming to add or subtract fuel based on what the air fuel ratio meter is telling the tuner
