How did you design the length and junctions, and correct them for the header inside diameter?
Have you dyno tested this configuration to make sure you have not impaired the power curve by altering the exhaust pressure wave timing?
Sound is one thing, performance another.
I kinda put this together while waiting for a decent system to come out, I guess EICMA show will tell, hopefully Arrow and Leo Vince will fill the gap.
I just couldn't deal with the 2 10lb cat filled cans any longer and as far as the Termis are concern, I've had them on my 1098S Tri. and I think the way the welds are done on the system and the way they fit on a bike is soo pathetic that I wouldn't bother spend money on. Also, the full Termi system is $3,200 give or take, this was done with less than $600 and I'd bet that on a Dyno it wouldn't be too far from what the Termis read.
My bike, my opinion!
