I am thinking of changing the exhaust system on my 72 CL350 race bike. The current "home made" by previous owner is fine, but I want to change the rearsets a bit and the exhaust is in the way.

What are others using?

Could you give me pros and cons of using the original high pipes? I know the mufflers are heavy, but maybe someone is using straigt pipes with baffles to meet the sound requirement?

I was hoping to make it to the track Monday and check out the other bikes, but unfortunatly thats not going to happen,

Thanks,
Jack

Jack,
My race system is the head pipes from some aftermarket noname setup for a cb360 that I had to modify to fit by lengthening on of the pipes. I then fed this into a 2-1 collector with an aftermarket,Maybe D&D, from a 600 sportbike. This abortion appears to work pretty well for me, but without putting it on a dyno who knows. I was running stock CB head pipes with some aftermarket baffled megaphones on it. This system makes much more seat of the pants power than that set-up.
We have had the discussion on here about head pipe diameter and JohnnyB. thinks that the stock head pipes are a large enough diameter to flow as much as the 350 needs. What I would like to try is the stock CL headpipes and a pair of JohnnyB.'s megaphones on it. I think it would look bitchin and work great. Most people that seem to know suggest that a 2-2 system mkes more power on the 350 than a 2-1. In my case, I think that my adequate 2-1 makes more power than a crappy 2-2. I would like to try a good 2-2 system.

FWIW

Scott,
I seem to recall that back in the day the Bassani had a good reputation for making power. I think that some of the factory superbike teams used Bassani pipes. This really gets into the 2-1 vs. 2-2 pipes and the 360 crank vs. 180 crank discussion. I haven't really given it too much thought since it makes my head hurt. I am considerng trying to make up a 2-2 high mount system for a 350 this summer that will exit under the seat. I will see what happens.
Back to your question about having your Bassani copied, I would like to see an affordable racing system out there that would give good ground clearance, reduced weight and better performance at a reasonable cost.
