Hey everyone,

I am just starting looking in to getting a full exhaust and a dyno tune (Woolrich)

What do I need and what do I need to look out for?

I was thinking Arrow header + Yoshi alpha slip on. Do I need more hardware beyond these? (I've seen O2 sensors and bungs mentioned but I don't know if I should just plug it off, run factory or get a different O2 sensor)

Should I buy the Woolrich kit for the GSXS or will a shop have everything I need? What if I want to go back to factory?

Thanks for any help.

Hello

Maybe no one has answered because it is best to first research the Forum as there is so much information to answer your questions, then if you need further details, start a new thread.

You can even start with a Google search, and you will see all the Forum threads come up. For example search "Yoshi Alha", or "ECU Flash"

In my opinion, it appears Dano's is the best mail-in flashing service (and you can call him and ask what options you have and need to do), and M4 full exhaust is the best performing aftermarket headers, unless you don't like the M4 muffler, then it is Arrow headers and a slip-on.

Thanks man, I am just super new and went through several forum posts and couldn't really get an idea of everything that I would end up needing. We should have a sticky for DIY and Projects where people can post their process on stuff.

The stock bike has a 12mm narrow band 02 sensor that is used on low throttle cruising and makes the bike run closed loop, i.e. the ECU keeps the bike really lean, good for emissions and fuel economy but bad for smoothness and response so the majority of bikes that have been flashed have it disconnected i.e blocked off

You only need a different 02 sensor (18mm wideband) if you are doing your own tuning on the street

Should I buy the Woolrich kit for the GSXS or will a shop have everything I need? What if I want to go back to factory?

Thanks for any help.
If you buy theWoolich Kit then you will have to tune it yourself as the ECU needs a licence to flash them and that licence is restricted to you and that ECU, so if you are having a dyno tune leave it to the tuner to purchase the licence (they won't want to tune it using your licence and hardware)
