Tune after Headers only?

I guess we'll find out the hard way next week. I'll report back.

I suppose depending on where on the fence you sit on the environmental spectrum, we've got the catalytic converter attached to the headers on North American cars. I like having them there because is drowns out the sound and the exhaust smell is not as awful. But on the other hand, it also robs the vehicle of its performance which is a sacrifice I'm willing to make.

If the sound is really bad, I'll swap back to stock headers. The low rumble of the FVD Brombacher Sound exhaust is nice as-is, so I can only be optimistic and hope the headers will make it sound nicer, but not necessarily loud and obnoxious.
