Getting ready to install my new MPI Stage 1 S/C. Got an A/F gauge and sensor to install. Where have you guys been welding the bung? I've heard of before the muffler, which will need to lay pretty flat, but I also heard of the right side muffler outlet.

Anybody have experience with either location?

Thanks,

Marco

Right before muffler.
 
You can put your o2 sensor b4 the muffler and still have plenty of angle without hitting the guard. I do this on my sc'd sleds with no problems.
 
That link should be a sticky. How about it Mods? Great info from Allen with pics for sensor locations
