Worth the Weight

So I've bought all the small tidbits for my bike that I can think of and now it's time to go for broke. Currently I have a CF Yoshimura RS-3 bolt on exhaust and I am looking to get a full exhaust. I have looked around for prices but just for conversations sake I will use Yoshimura.com as a reference. The CF/Stainless Full Exhaust is about $900 and the CF/Titanium Full Exhaust is about $1600 give or take a few. I've emailed them asking the weight difference and the difference in power gains between the two parts but have yet to get a reply and it's been over 2 weeks.

Does anybody know the weight difference between the two systems or the gained horsepower that a full sytem provides compared to a bolt on?  

HP gains depend on the bike.
keep in mind you'll need a power commander with a full system, so get the cheaper one.
the difference in weight between a full titanium or stainless is usually a couple pounds—not worth the hundreds of extra dollars.
titanium vs stainless systems will make the EXACT same power though.  

Alrighty, I have never just held a chumk of titanium so I have no idea how much it weighs compared to steel, I just know it for being stronger. I knew the power gains are the same between the full sytems, but I wasn't sure exactly how much lighter titanium was than steel. I will go with the stainless system when I get to it. The power commander will be my next investment then when i get the full system i will just remap it. thanks again  

You would be better investing in a trackday and making your skills as a rider better then the bike.  The titanium are usually just thinner wall tubing to make it lighter.  Check out Bazzaz Engine Performance stuff too, they make a nice product as does dyno jet

I have never been to a track and I really don't have the time to. I have been riding for over six years and so far I have been lucky enough to have never let anything but the rubber touch the road. I have learned how to ride by getting out there and doing it and by reading and asking questions about it. I am pretty confident in my abilities as a rider without a track. I just want to get every little bit of power out of the bike as I can with each little new part I can afford. New wheels are in the near future. We're always getting better as riders still but to build a small beast while learning never hurts.
