Aftermarket Mid-Pipes

[j_lutter31]

I have been thinking about maybe getting a mac pro chamber OR mid pipe. But I'm curious where the O2 sensor mounts. Is there a bung in the mid pipe for it or is it in the header somewhere?

One other thing was....Does the exhaust line for the smog pump come from the midpipe? My harmonic balancer went out and broke that line near the pass. side valve cover. Right now I just wrapped it in header wrap to keep it from dumping exhaust into the engine bay but it would be nice to completely remove the line.

the o2 sensors plug into the mid pipe on the stock setup. if you have long tubes, which i assume you don't, they are in the header.

that line can be plugged up if you don't run your smog pump. if you plug that line, i'd remove all the smog stuff while your at it.

So do most aftermarket mid-pipes have a bung for the sensor already?
