I do not really like the stub exhaust on the Sonerai and am going to replace it. Initially I was going to do a 4-2-1 or tri-Y exhaust but at the engine speed the engine will operate at I am thinking that a simple 2-1 per side will be more than adequate. I would use 1.5" SS tubing into a 2 into 1 merge collector with a 1.75" outlet, exiting under the rear of the cowl.
Thoughts?
