Title: Aftermarket Exhaust W/ Fuel Injection
Post by: big blue on September 19, 2012, 02:35:35 AM

Hello all:  If you wanted to install an aftermarket exhaust system on a scooter with an oxygen sensor; would you need a system which had a screw in mount for that sensor?  If that is not an option could you buy a free-flow muffler and mount it AFTER the sensor?  ???

Yes and Yes

The stock system needs to see the oxygen sensor for closed loop operation
so you need to add it to the full system or just change the muffler.

When i added an oxygen sensor to my Leo Vince exhaust it was just drill a hole and weld the nut to it. :)
Of course, the sensor should be placed before the catalyst, if you have one of these on your aftermarket exhaust. :D
