MPGomatic · 08-03-2014, 01:43 PM

I want to install a second wideband 02 sensor into Slambo to run a dedicated Air/Fuel gauge (largely to monitor Lean Burn) ... but I'm looking at the OEM exhaust manifold and I'm not sure if it'll be possible to drill it and add a bung.

Is anyone running the Magnaflow manifold/cat?

I'm wondering if it might work for this (could it be drilled on the reverse side?) ... either that or go the header route. I'd like to avoid the expense of replacing the entire exhaust (it's in okay shape) and don't want a flatulent muffler. (We've already trashed one of those.)

If I end up going with a header, I'll spring for before/after dyno tests.
