Performance Duals
Why has no one ever designed a dual exhaust system with the performance headers that come with the 4 into 1 systems. HMF did a sytem like I'm speaking of for the Busa. Plenty of us big bore sportbike enthusiasts love the look of the duals and also like the performance advantage of the tuned headers. I'm well aware that no true dragracer or horsepower junkie would ever think of such blasphemous dual exhaust speak. And of course the added can (or MEG) would add pounds but for me and I'm sure many others, the trade off for the symetry and throaty sound of the duals would be worth it. Just a question and an appeal to those beloved exhuast manufacturers.
I can vision the dual SMEGs breathing on a cool morning or think of what the new M-10 series shorties would sound like at full rip.
Can anyone relate?

Thanks Steve. I'm torn between all-out performance and the looks of the duals. I had a full Muzzys stainless on my ZX-11 and loved the sound and performance. I guess I want what's not yet available. Hmm. How much weight did you save going to the carbon Gen-3 total. Do you know the weight of the mid-pipe and carbon can?

Like the look of duals and want performance too. That's easy. Get the duals you want. Keep the factory header. Pull the secondary butterflies and remap with a PC-III.
Less money and work than a full system. The look that you want and a huge gain down low where you use it. Need more? 16 tooth front sprocket and 42 or 43 rear.

That's definitely an option, and would add a lot, but with the full system you get more performance than slip-on's and lose a lot more weight. I'm sure Brock and some of the other guys could come up with a dual setup that's a lot better than just slip-ons, but I'm sure most of them don't see a big market for that.

Understand - dual's are strictly to meet AIR and noise restrictions. Not performance.
A few people think they look "cool" but really they suck.
They suck on the Busa and they suck on the 14.
If you want to bring your 14 to life, the stock exhaust (yes, the whole thing) has to be gone.
It's a pig weight-wise period.
Lose 35 lbs on your 14 and you will be born again. Trust me on that.

ive never weighed a set of titanium duals but they probably weigh less than a stainless brocks system... and an extra pound or so wont make much of a difference on a heavy ass bike like the zx-14.

I'm one of those MANY people that don't think the duals suck. If nobody likes them, I guess Area P and Muzzys and several other exhaust makers wasted a lot of money on R&D to bring them to market.
The weight thing is REALLY out of control. I keep hearing how you can save 35 - 45 pounds by going to a 4 into 1.
To quote Brock: "THE STOCK EXHAUST WEIGHS 37 LBS 2 OZ.?!" Too lose 35 pounds, you're gonna need a replacement exhaust that weighs 2 LBS 2 OZ. I believe that he said that his Gen 3 system weighs 12 lbs. 37 - 12 = 25 lbs saved.
My Area P DUALS saved 15 pounds, so I'm carrying a whopping 10 more pounds. That could be worth a half a 1/10and the 10 extra HP for the 4 into 1 maybe another 1/10, so for the drag strip, it's worth it. For the street, essentially no difference. As someone already pointed out, there are other mods for the street that outweigh (pun intended) the benefits of losing the duals.
My 2.2 cents.

You only need two tools: WD-40 and Duct Tape.
If it doesn't move and should, use the WD-40.
If it shouldn't move and does, use the duct tape.

Okay, some like the duals for symmetry looks and sound. I accept that and if that is your thing, go for it!
Consider this; why pay for a can that you don't need? Use that money of the second can towards the higher performing pipe! You get more HP with less weight! Another added benefit is without the can on the chain side, it makes it easier to clean the dirty side of the bike. I would never go with slip-ons, not worth it IMHO.

Thanks everyone for your input. Lucky14, I was thinking of going with the Area-P duals and upgrading to light weight wheels as a trade-off. CaptainZX14, I understand the dirty side issue got used to that with my ZX-11 that had the left side exhaust. Phytrax, maybe I'll get the Brock's header and have a local shop fab to the duals.

I've heard some guys simply cut the ss stock exhaust, pull the cats out and re-fit the end caps. Also another way to save weight, cheaply?

one thing you will get more of with duals is vibration, the resonance between the two pipes will be buzzier compared to one. i switched to a set of bub duals on my old cbx and it lost some big end and the sound was not as sweet as the winning performance 6 into one. no performance 4 cylinder exhaust maker wants to make a system that slows the bike down. go for slip-ons.
