4-4 exhaust question

[sharky]

I'm after what looks like a 4-4 exhaust for the project bike...wondering about a balance pipe that links all 4 under the motor...or 4-2-4 ????
Going to see about stamping out 2" supertrapp type discs so I can run 4 upswept cans without frying the girlie on the back.. (she's hot enough already :) )
I know 4-2-1 etc is best but I'm looking at the style over function...maybe..:confused:
Any thoughts oh great collective ??

What about 4-1-2 the splitting into 2 of this type on each side http://www.ebay.com.au/itm/Jardine-GP1-Polished-Slip-Exhaust-System-Muffler-Yamaha-YZF-R6-06-07-08-09-/180725621501?pt=Motorcycles_Parts_Accessories&hash=item2a141622fd#ht_2580wt_1271

ok the best way to do this would be to have 4 header pipes then have a small collector then your 4 pipes out thats the best way im sure there are other ways but this is just my thoughts

I'd go 4-2-balance pipe-2-4 , you could just use a set of 4-2 headers with a balance pipe then use the 2-4 pipes off a second set to split it back up again. TI would make it look sexy as, you could get 2 sets of Ti headers from evilbay for fuck all. Cut and tig, Ti mufflers modded to supertrap setup would set the whole lot off real nice.

The 4 to 2 balance pipe would be under the bike, and if you get the 2-4 close to the balance pipe from the front and rear it would prob look like 4 to 4.

The 4 to 2 with balance pipe would prob give you a broader torque over a wider range than 4 to 1 but with less top end.

Why not go traditional 2 up 2 down 4-1 to get the performance,
then back into 2 with dual can's on each side.

Collecter will get you the best performance
(I was told why "flat" 4-1's arent great but cant remember now)
and if you keep the pipes after a decent size it wont be strangled.

Your still carrying the extra can's/weight in the name of vanity,
but hey, whatever floats your boat....;)

[sharky]

The cans will be minimalist...4of .maybe 200mm long x 50mm od ...probably lighter than most twin muffler systems.
I can experiment on my current bike to see what works

So similar too a smaller, neater version of the
1st of the new generation Z1000's ?

I'm looking at style over function.

Why not go with twin 6" diameter chrome vertical Truck Stacks with turnouts & raincaps?

I'd say closer to the look of the 7 yr old Z1000's as they had smaller pipes. New ones are just ridiculous.

Thats what I meant.
1st of the "new" liquid cooled one's,
The first Z1000 after the old GOOD one's.
