Hello everyone!

I'm about to swap pipes, gut the airbox and rejet carbs, so I've purchased an Innovate A/F ratio gauge, here: http://www.innovatemotorsports.com/xcart/product.php?productid=16290&cat=262&page=1 to be more accurate.

I'm planning installing the sensor on the cross-pipe (pipe crossing both exhaust manifolds pipes). That means, drilling the pipe in order to weld the kit bung.

Here's my question, actually, two questions...

1- MUST I remove the right exhast manifold in order to drill the cross-pipe or can I drill the pipe without removing it?

2- How accurate would the gauge readings be, once installed on the cross-pipe?

Thank you!!!
