I have an old Daytona pipe and the baffle was huge. I liked that sound quite a lot but I dunno it was a 4-2-1. Strange looking pipe but on the street?
I think that if you get anything it will work fine as long as it is tuned/jetted/timed properly. There will be differences but on the street most people won't even worry about the nth degree. If you are asking then I assume that to be the case.

Dyno your build (1015) with each pipe... This way you'll know if "bullshit" or not on the manufacturer claims of increased horse power...
On a different note regarding your home built baffle...
Notice any performance differences?
Stay with same size baffle openings?
Notice back pressure differences, popping, acceleration lags, flat spots in response etc... ?
Straight or twisted baffle design?
Have any images of the baffle you made?
Seriously, interested in how you did it or what you came up with in design but truly interested in noticed performance differences...
We all need to keep in mind there's also the science of exhaust system calculations (more then just a baffle) that are incorporated into each design such as pipe dimensions, riser lengths, collectors, exhaust lengths and sizing for tuned power bands.
All of which increase performance/HP in any bike.... Sure, there's a whole slew of other variables (pistons, compressions, head work, carbs, gearing etc...) no doubt...

if a person has a special project, then 600.00 is nothing....but for a good---wait???---great
!!!! used -condition- header...one only has to be patient and watch auctions....
hey if you like your old pipes then good for you...not everyone eats the same ice cream....thats why they make 31 flavors....
and as far as which header is better...depends who you ask....and how you ride,and where you ride,and what you ride,and what the mods are
is superman able to beat up wonder woman if batmans not there and auqua man helps the loser????....

If you want a 4-1 pipe. Keep watching ebay ,I bought a kerker in good shape with no baffle for $75. Ordered a new baffle for $99 and it sounds great. The key to ebay is being persistant. Sooner or later you will find a deal .

I just made a baffle for a kerker pipe for a 1015cc. It sounds awesome and is quiet. I think it will not perform so well on the highway as my old extended 2to one pipes. If it doesn't, then whats all the hype over four into ones? The price for these pipes is ridiculous. Pipes that cost more than some whole bikes do. I guess I'll see how the scavenging performs. Or not. Has anyone dynoed vance and kerker and actually saw the difference in power out? I just don't believe there is a difference that one can feel. They are almost the same pipe! The buck stops here! I'm no longer sold on all the catch paragraphs under the listings. Seems just about everyone is sold out to propaganda. 600 dollars for a pipe? Are u kidding me? For why! I could probly put my old pipes on someones modded bike and it would make more power then these so called performance pipes. Can't help but notice a vance pro pipe is just one BIG pipe with nothing fancy. Just wide open and oh yyyeah, FOR RACE ONLY. whOO hOOO! I call blllsht. If my grandpa was alive I'd ask him "Grandpa? Does everyone lie? Or am I just the stoopidest blankedy blank on earth?:blink:n :huh:
Why do you "think" it won't perform as well as your old pipe ?
Most likely there won't be any difference that you can feel...other than the 20+ lbs that were saved.
I'm not sure people are looking for, or expect, a $600 increase in performance when they buy a Kerker, it is more likely that what they are looking to purchase is a period correct piece of nostalgia. For some, that alone is worth $600....for others it isn't
Everybody here is looking for something different from their 30 year old motorcycle ownership/riding experience. To each his own.

Do it your way man. It's your bike. You could even put a car baffle in it from a honda if you like. Or mate half a d and d pipe to another exhaust like I have seen a few do on here.
