Got my headers today & question 'bout crank scrappers

[b1gmoose]

I picked up a set of Ireland Engineering Shorty headers (not equal length :-( can't afford equal length in the ball park of 500$ used).

I also got the straight pipes and a near new o2 sensor. Picked it all up for 100$ even. Was gonna be 125$, but the seller cut me a last minute deal. Normally these are 350$ new so I'm happy even though they are used.

My next project (gonna take a few cases of beer to a friend) is to have them put on the car. Have to have the straight pipes cut so it can be welded infront of the catalytic converter. I would love to remove it, but it has to be there for the visual inspection for VT. Doesn't have to operate, and there are no emissions on an 89 vehicle. But I should keep it there anyways because it does get rid of nasty chemicals.

Hopefully I will see a moderate (.5mpg) increase in fuel economy. And even if I don't, the car will sound better and it wasn't much $$$ out of my pocket.

Any ideas on how a highflow-freeflow catalytic converter will boost fuel economy?

Also, has anybody run a crankscrapper in their car? I'm thinking about putting one in my car, just not sure when I'll have time time to install it. I have a special oil pan with a hole in it for the front axle to pass through for the front wheel portion of the AWD setup. So it will be labor intensive and I may pay a mechanic to do it for me, if I can estimate some gains from it.
