the stock quad pulled 40 HP (with airbox lid ON and exhaust plug IN)
after the Barker Exhaust was on (airbox lid OFF) it pulled 45 HP and 30 FT LBs of tq

we put in the quiet core and it sounds GREAT!
only lost 1/2 of a horse and just over 1 ft lb of tq
(quiet core 44.5 HP 28.? ft lb tq)
here is a video of the run from my VholdR Helmet cam
(that is Tim Barker on the quad)

it sounds REAL good in person, kinda hard to hear in the video

comments?

I have other video.. just takes some time

PS.
I should note that we DID install a PC5
and the fuel mix was DAMN close
only took minor adjustments to make it perfect

Sounds pretty clean through the powerband, nice deep done.

KB motorsports has it listed on their site, I believe MSRP is 889.00 though. They usually can get you a good price so i'd check there.[/b]
its discounted right now to 800, lol i just dont know if i want to spend that much money on that exhaust, but its the one i really like, so im sure ill end up getting it

well it looks like ill be ordering the SS version if i go that route[/b]
I can say I blame you, IF* there is some sort of corrosive downfall to using carbon fiber or carbon kevlar as a casing, then why use it? I kinda like the sparks, but i'd like to see some more conclusive dyno results on each system before I make my decision.

I have all the dyno sheets.. what do ya wanna see?[/b]
Post them up!

I'd be more interested in the dyno's of competitors systems, it looks like the bolt on stainless system gave 5-6 hp. I wanted to know what the sparks or dasa can put down, it's probably close enough for me, but i'd like to see all the graphs. It's hard because there's different dyno's and such, and some sheets are claiming more or less hp without knowing all of the capabilities.

i saw the two bros dyno sheet and needless to say im not impressed at all. it said it was only making 40hp with a full system...
i would like to see a dyno sheet of the barker. so far im looking at the barker, sparks and the trinity.

More vids I mean. haha :icon_cool:

I've got to be honest, I'm on the fence between this and the HMF. I like the CF case and I don't care too much about the warranty, but standing behind the craftsmanship either way would be nice when shelling out 300 more than the competitors.
