What was the best header for GS1100E

I know there are a lot of different header designs for these bikes. Are they all 1 1/2 inch primaries. What are the best designs. I see the Yosh is pretty sought after.
 
Stainless rocks, titanium that would be sweet too. I was wondering is any of the pipes stood out in their design. I am seeing a lot of 1.5 inch tubes can anyone chime in what size theirs is. Anyone want to show off their pipe and tell about it.
 
Looks like my all time favorite pipe performed well. I always liked the look and sound of the Supertrapp Stainless.
 
Wow the stock pipes do great. I am going to have to look at a supertrap that is on an 82 GS1100E parts bike I spotted locally for sale.
 
Speaking of finding one. Tingates in Oz where the pipe to use in racing in the 80s. Closely followed by the Megacycle. Ill edit this when the sun comes up for Primary tube Dia.
 
Actually stainless 4:2:1 is best for the street, but you will likely have to adapt something from a GSXR or Bandit to get this onto your GS. Most all of the older pipes are 4:1.
 
Anyone got a beat up Bassani, or yosh that is unusable for a pattern.
 
The problem with the chart Ed posted is that it is MISLEADING. The difference is in REMOVING the airbox & installing a Stage 3 jet kit & with pod filters is a HUGE difference! More airflow, with more fuel added, means more POWER! For a STREET pipe, the V&H, Kerker or street Yoshimuras make good power. The Bassani or the 3 other pipes, WITH competition baffles, will make even MORE power but are LOUD! The stainless Supertrapp is the easiest to keep looking good over the long run as anything chrome or painted WILL eventually rust. Any 4 into 1(except MAC, which is garbage!) will make good power when jetted correctly & have a nice tone. I have jetted GS1100s & 1150s with just about every pipe out there & have seen HUGE improvements over the stock pipes, power wise.

Bought my 1100 with V&H, found the airbox lid missing, tried to order one!

Just ****ed that my mechanic neglected to run it on the dyno before he rejetted it for the pods I installed.

I know the 108 HP is a crank claim (get it? :xsmilie_mrgreen:), so I consider the 99.3 an increase. Funny thing is, the new, improved (I assume) torque number matches the original claimed torque, 68. So I guess torque increased more than HP with the jetting and pods?
 
Ran a bunch, My 2 favorites were the Vance and Hines Header with out a baffle and also the Kerker Pro pipe with No Baffle, Never had a noise ticket either but she would pull 12,600 in top gear on the 401 in evasion mode, sweet sound I miss hearing that . Mike
 
That header chart 2 only horsepower increase? That seems wacky? If so how would a big street motor do with stock pipes HP wise? Just wondering. Less Police chases with quiet exhaust as you can silently slink away ha ha Mike not that anyone does that nowadays!!!
 
There is nothing misleading about the chart I published. The data was collected by Joe Minton, who published a bunch of great magazine articles back in the day about hot rodding UJM's.

Modding the bike through the use of pods and more extensive rejetting is another step in the modding process, so knock yourself out and mod away. I think Minton published some info about that too but as I recall, the real gains came when moving to larger than stock carbs.

I'll try to dig into my magazine archive this weekend and see what I can find.
 
I found an old Bassani on eBay. Had to knock the dents out of it, but it sounds good with a SuperTrapp silencer and 14 plates.
