Hello, I’ve heard that Zard has a remap for this (full) exhaust. Haven’t seen it on their site but this may be the sound and performance you are looking for.
Far too quiet for an aftermarket performance exhaust. Ridiculous price & design, it doesn’t flow better than a single canister, for far less money. Only a presumed status image is it’s only attribute. Also the twin Ti cans are heavier than a single aluminum one.
Anyone who has ever had the muffler off knows that it's not much louder without it. I think it's an absolute waste of money. more interesting: who builds an under seat that frees up the rear wheel again. you might consider spending money on it
