I always wonder cause I keep hearing mixed reviews some say it lowers HP some day it's like a full exhaust and some say it offers nothing but sound lol even 1/2 way to a full exhausts benefits and I'd do it better than spending 640$It's going to be pretty damn similar to a full exhaust.
I'm sure the extra $300-400 in your pocket makes up for it!I would have been quite happy with simply the decatted header, if I didn't have to come out to my bike every day and see that pretzel shaped header poking out from the front.
Looking at area p's dyno charts, the gains are pretty big. http://areapnolimits.com/images/product/ninja-300-dyno-high-mount-areap.gif Maybe knock off a little hp because their customers headers are designed better than a decatted stock exhaust, but we're still talking 3+ hp gain.man oh man the amount of stuff around you guys will do to get an extra half of bugger all hp out of your bikes , its just crazy.
honestly if you really want to pull your exhaust off the bike and cut the cat open & decat it and reweld it and put it back on , honestly you would be better off buying a full system to begin with, iti will save you a lot of stuffing around and the stock exhaust is pretty easy damaged, ask Jeff he knows, whats why he bought a full system in he first place
Was contemplating doing the same, would definitely help. But then would be pretty hard to pass off as being a stock header if you ever needed to.....I'm sure the extra $300-400 in your pocket makes up for it!
I've got a tuner and a slip-on right now, trying to find someone (reliable) to do the decat for me.
I'm kind of curious if it would be worth cutting out the bellypan where the cat was and putting in a a same length pipe of the same diameter of the rest of the system. If I'm going to have it cut open it wouldn't be much more difficult to do.
