Im a new 2013 ZX14 owner and want to put on two brothers exhaust. Is it necessary to add a power commander like I had to on my M109? Thx

no not necessary, many of the maps are actually taking fuel out.

I put full Yosh R-77 on my bike. It runs spectacular with no PCV or additional fueling changes. As far as performance increases, I have no idea. I'm pretty sure it's not any slower, but I don't know it's any faster either. Sounds freakilicious!

I'm sure a custom tune would be beneficial. But unless you're racing probably not worth the cost. Second best would be a custom map from someone like CBlast which is highly tuned, just not specific to your particular motorcycle.

Thx so much for the info and can't wait to finally ride and put the exhaust on it. Thx again.

Nah, don't need to change anything. Put it on and enjoy the new sound!!!

Hey Rusty... Did you buy your exhaust yet. I'm thinking about selling my Two Brothers CF slip ons along with the PCV. I also have the green power tips as well. Like new... Bike has 500 miles.

I am in the market for a pair of slips, whats the deal for used 2 Bros and why are u selling them after only 500 miles?

They came with the bike which I just bought with only had 170 miles. I'm going full system and Cblast over the winter. I will sell the slips.. Tips and PCV for 700. Not a mark on anything.

Only interested in the slips, just gonna have cblast flash the ecu

Cheapest I found new is 629 so how does 500 sound? If you want to see them go to the newbie section and there is a pic of my bike there.

Do I hear 450

GunShow, pm me please Cant find you on the list
