Greetings,

I'd be interested to see pictures of your O2 sensor installation for the Roadster. My concern for placing the O2 sensor bung now is how it will impact the body installation when the time comes to mate the chassis to the body.

The constraints for the Holley Sniper EFI is that the O2 sensor be installed 1 to 10 inches after the collector and have at least 18 inches of exhaust pipe left after the sensor. Also, the O2 sensor cannot be installed at the bottom of the exhaust tube.

This will be a clamp-on bung installation on the stock FFR pipes. Eventually I'll be going with GasN pipes and will have them install a permanent bung, so I want to get a location that will ultimately work for them as well without doing more modification to the body when I make the switch.

Thanks for your input.
