Turna exhaust experience
« on: July 12, 2016, 06:53:24 PM »

Hey guys.

I want to order a Turna exhaust for my 2007 efi, but wondering how you connect the o2 sensor. Is it build only for one o2 sensor in one of the pipes? If so, can it run without problems and without installing a powercommander?

Thanks :)

'07 is not an EFI year model. Are you sure about this?

Aside from that, you can add an "O2 sensor bung" to any exhaust, but you will probably need to pay a welder to fit it. It's just simply a stainless steel nut, of the right diameter. You drill a hole in the exhaust and then weld the nut into the hole.

Try to find a place where the O2 sensor will fit and not be too obvious.

It actually says 2007 in the production year of the bike even though I haven't read anything about efi models from that year. Kinda weird actually. I'm from Denmark and bought one of the two last leftovers from this model 1 year ago.

The Turna exhaust already got a hole for the o2 sensor as I know, but wondering if it only gets the reading from 1 cylinder since it's 2 separate pipes? Do you think it will turn out fine then and still run smooth if it only reads from 1 cylinder? :)

No idea about how well an O2 sensor would function in that situation. I have never done it.

I think you need to make sure that your bike is definitely EFI first.

Like I said, 2007 is not an EFI year model.

the thing about used bike is you never know what the other person did to it.
its best to run the after the pipes turn into one. the 09 I have the o2 sensor is right behind the foot peg.
The my 13,15 gtr 250's have 2 o2 sensors.

When you install the Turna pipes you keep half the front header pipe with its O2 sensor so the Turna Pipes only need one O2 sensor for the rear pipe.

Also there are two different sized O2 sensors and the Turna pipes have the smaller one. If you have the bigger 22mm sensor then you can take the pipes to an exhaust shop and they can cut out the bung and weld in the bigger one pretty easily. The bigger one is the same size as a standard car O2 sensor.

GV650 did not have EFI in 2007, I believe it was 2009 when EFI came into being
