    R&D Exhaust spacer with O2 Bung installed..

    Is this a better place to measure a/f ratio since it is right off the exhaust manifold? I know this allows you to remove the supercharger without moving back the waterbox. Will this fit with the thru hull ? I seem to have about an extra 2" in between my thru hull fitting in the rear, and the pipe that connects it to the waterbox. Obviously it would be cheaper to weld a bung in the J pipe, but this seems like an easier bolt on solution? I like the idea of being able to remove the supercharger without moving the waterbox, and also I want to put in a O2 sensor...

    good luck, I think ZERO R&D went into this product, the 02 sensor will hit the exhaust manifold bell. You have to at the very least drill a whole through the bell, but it will thrn read lean because its not in the exhaust stream. It is a POS, don't waste your money.

    When I saw this part I was wondering about the fitment issues with thru hull exhausts and with the aftermarket waterboxes.

    I guess you could cut the bell off your exhaust manifold? I've read that it doesn't really do anything, and that people do run without the exhaust bell with no issues.
