Quote: What if you gutted the pipes on an 09 version, would you need to buy a fuel commander to alter the EFI?
I currently have a carbureted Yamaha, and one of the biggest reasons I stopped at removing the first baffle is because removing the cats and final baffle required a rejet, which I neither wanted to bother with, or pay for.
Hi, I'm rookie. Bought BA this summer (2010). It's got EFI. I didn't see anyone answering this question, so I thouhght of reposting it, cause I'd be intresting to take the end-plate (and baffle attached to it) out and wonder if adjustments in EFI are required.
